Sanctuary
and Coast Guard Team to Protect the Environment
How
can you protect 638 square nautical miles of open water and the
valuable marine resources they cover and hold? For a newly established
Sanctuary with a minuscule staff and a large mandate, the answer
was to find some like-minded partners. Relief came in the form
of the United States Coast Guard.
Eyes
in the Sky and on the Water
On January 5, the Stellwagen Bank National Marine Sanctuary and
U.S. Coast Guard officially agreed to increase enforcement to
protect endangered species and to uphold a set of Sanctuary regulations
established when the Sanctuary was created in 1992. Numbering
only three, the Sanctuary staff is hard pressed to make regular
trips to the offshore waters and monitor activities there. That's
where the Coast Guard fits in.
With
its regular presence in the skies over the Sanctuary and in the
waters from Cape Cod to Cape Ann, the Coast Guard provides added
observers needed for this marine site at the mouth of Massachusetts
Bay. Under the agreement, the Coast Guard now schedules one to
two special overflights each week dedicated to Sanctuary concerns
and adds routine surveillance of the Sanctuary to all other ship
and air patrols. Coast Guard patrol boats may also stop and board
vessels caught fishing or dumping illegally or threatening endangered
species.
Partners
in Education
Although the Coast Guard's expertise and capabilities in enforcement
are invaluable to the Sanctuary, other aspects of Coast Guard
operations have also provided much needed assistance to the Sanctuary.
Regular crews as well as the Coast Guard Auxiliary are distributing
information to boaters about the Sanctuary along with important
boating safety information for these waters, particularly guidelines
for whalewatching. When endangered whales are spotted, the Coast
Guard broadcasts radio warnings, and has provided support for
operations to disentangle whales found caught in marine debris.
The
public information specialists of both organizations have worked
together to develop a public service ad for television with the
Boston University Ad Laboratory about endangered right whales
in the Sanctuary, and to co-host several press conferences about
joint operations. Sanctuary staff members have, in turn, traveled
to Coast Guard facilities to train boarding officers and others
on aspects of the national sanctuary program and environmental
topics related to Coast Guard operations. Another partner in the
formal agreement between the agencies is the National Marine Fisheries
Service which is training Coast Guard crews in enforcement requirements
pertaining to the Endangered Species and Marine Mammal Protection
Acts.
Research
Too
In an effort to better understand who uses the area, the Sanctuary
has contracted for a user study (see related article on page 2)
for which the Coast Guard has supplied videotaped overflights.
Research requests for ship support have also been provided on
an as needed basis, and when regular Coast Guard operations allow.
Boater safety and the air/sea rescue capability of the Coast Guard
are never compromised during these Sanctuary-related projects.
The installation of a radar system (once used in the war against
drug traffickers in Florida) at the Coast Guard's regional communications
center in Marshfield will give the Coast Guard and Sanctuary a
complete overview of the number of vessels in the Sanctuary at
any time, thereby simplifying data collection for the user survey.
Coast Guard facilities have also served as bases of operation
for Sanctuary-related research cruises and meetings.
"We
couldn't have found a more efficient and accommodating partner,"
notes Sanctuary manager Brad Barr. "Our efforts in interagency
cooperation break new ground and demonstrate how organizations
can work together for the common good. Not only is this economically
advantageous, but it allows each organization to specialize in
the areas of its own expertise," he said. "We look forward to
continuing this cooperative relationship and building upon it
in the future."
Tidings
Welcome
to the first issue of Stellwagen Soundings, a new publication
of the Stellwagen Bank National Marine Sanctuary. The Sanctuary,
the first of its kind in the Northeast, and one of only 12 sites
nationwide, encompasses 842-square miles (638 square nautical
miles). Within these waters can be found an important and intricate
marine ecosystem that includes four species of endangered whales
as seasonal visitors, important commerical fish stocks, and a
host of interesting creatures, both large and small. Sanctuary
History
The
history of the Sanctuary began in August 1982 when a group of
concerned citizens put the finishing touches on a proposal to
designate the area around Stellwagen Bank as a National Marine
Sanctuary. The National Oceanic and Atmospheric Administration
had invited the public to nominate sites for addition to the national
system and representatives from the Center for Coastal Studies
and Defenders of Wildlife answered the call. In 1983, the site
was added to the list of nominations that met basic criteria,
sebsequently becoming an active candidate in 1989. Three years
later, in 1992, Congress officially designated Stellwagen Bank
as a National Marine Sanctuary.
But
in some respects, the history of the Sanctuary began at the end
of the last ice age, as the retreating glacier left behind deposits
that became the Bank. This area -- located at the mouth of Massachusetts
Bay in the southwestern corner of the Gulf of Maine -- has, for
eons, been a productive area, filled with a rich treasury of marine
life. Those who fish for a livelihood have long recognized the
area for its abundant fish and invertebrates (such as lobsters,
scallops, and squid). Even before humans cast there nets and lines
into the waters, whales, seals, sea birds and other creatures
sought out the bounty of the Stellwagen Bank area.
For
those of you visiting the Sanctuary for the first time, enjoy
your excursion. For those of you who have never been out to this
portion of the Gulf of Maine, we encourage you to learn more about
this fascinating place and hope you will one day have the opportunity
to explore it yourself.

What
to do when Oil Spills and Whale Spouts Meet
The
National Marine Fisheries Service and NOAA's HAZMAT (Hazardous
Materials Response and Assessment Division) sponsored a one-day
workshop at the Stellwagen Bank National Marine Sanctuary in May
that looked at the ramifications of an oil spill in a whale habitat.
When corraling the oil is impossible, what can be done? Do cleanup
personnel disperse the oil with detergents? Do they burn it? Do
whales understand the sound of a fire and avoid it -- this being
an unknown phenomenon in the wild? Can whales be chased away from
the site of a spill by the sound of orcas (killer whales) -- the
only commonly observed predator of great whales (albeit juvenile
whales for the most part). Representatives from the U.S. Coast
Guard, whale research institutions such as the New England Aquarium,
and others discussed the possible scenarios, possible solutions,
and trade-offs involved in each method. Over the next few months,
the National Marine Fisheries Service will develop official policies
for all contingencies based on these inputs and other suggestions
gathered at similar fact-finding sessions.
Sibling
Sanctuaries Cooperate to Protect Humpback Whales
Where
do the humpback whales go in the fall? Like many human residents
of New England, they go south to the Caribbean. The whales of
Stellwagen Bank join their breathren from elsewhere in the Gulf
of Maine, Gulf of Labrador, Newfoundland, Greenland, and Iceland,
and travel to the warm, sheltered waters of Silver Bank and Navidad
Bank off the Dominican Republic. This important breeding and calving
area for humpback whales has been designated a National Sanctuary
by the Dominican government, which unfortunately has only limited
resources available at this time to devote to this conservation
effort. In order to help protect the species at both ends of its
migration corridor, Brad Barr, manager of the Stellwagen Bank
Sanctuary serves on the Silver Bank advisory board. The Stellwagen
Bank Sanctuary will also help develop educational materials that
both sanctuaries can use. An additional link between the sanctuaries
will be an hour-long television program on humpbacks, produced
by a crew from the Venezuelan television series "Expedicion" (the
show has an international distribution and is scheduled to be
shown on the Discovery Channel). The filmmakers plan to film at
Stellwagen this summer; Silver Bank filming was completed last
winter.
All
Tied Up and No Place to Go -- Disentangling Whales
When
a whale gets caught up in nets, who do you call? The answer's
not so simple. Until now, reports have been going to local police
and fire rescue departments, the U.S. Coast Guard, local aquariums,
local wildlife refuges, and whale research institutions. The Stellwagen
Bank Sanctuary is working with other organizations in the region
to develop a disentanglement network in the Gulf of Maine; other
participants include the National Marine Fisheries Service, the
U.S. Coast Guard, and the Center for Coastal Studies. Such a network
might include an emergency response team that could be flown immediately
to entanglement sites and an 800 emergency call-in number for
entanglement sightings.
Kiosk
Goes Up in Provincetown
A
new exhibit showing the wide range of species at the Stellwagen
Bank National Marine Sanctuary and the marine food web will have
a summer installation in Provincetown at the State Pier. The free-standing
kiosk was produced for the Sanctuary by the Center for Coastal
Studies. Copies of the graphics panels are also going up in the
Cape Cod Museum of Natural History in Brewster and at the Sanctuary's
headquarters in Plymouth.
Sanctuary
Considers Experimental Closure Area
Fisheries
management decisions have been made over the past decades without
a complete understanding of what happens to the seabed when fishing
gear sweeps across it. The effects of gear on the benthic (sea
bottom) community of living resources is little understood, as
are the similarities or differences of natural phenomena, such
as storms. A team of researchers has proposed a five-year research
program that would call for the closure of a small section of
the sanctuary, to compare the effects of fishing (primarily dragging
and trawling) in an area of diverse habitats just outside the
closure area to a geologically similar area where fishing is not
permitted. After a series of public meetings , it was clear that
a closure of part of the Stellwagen Bank Sanctuary, in addition
to existing closures on Georges Bank and southern New England,
would be unacceptable to many of the meeting attendees. Based
on comments received, the science team has decided to delay any
further discussion of the experimental closure until the New England
Fisheries Management Council proposes its overall plan for groundfish
management. Once that decision has been made, and if the science
team decides to proceed, there will be a second series of public
information meetings, and, perhaps, a formal request to the Fisheries
Management Council regarding action in the experimental area.
Sanctuary
Field Guide Published
A
240-page, full-color field guide to the whales, birds, fish and
other marine life of the Stellwagen Bank National Marine Sanctuary
has just been published. Filled with stunning photographs and
artwork, the book delights the reader with the rich treasury of
the Sanctuary's resources. Sections of the book, written by Nathalie
Ward of the Center for Coastal Studies and printed by Down East
Books, cover whales and whaling, fish and fishermen, sea birds,
and the food web. The first edition retails for $14.95; copies
of subsequent print runs will go for $16.95 each. The book is
available at many of the stores affiliated with whalewatch operations,
the Center for Coastal Studies shop in Provincetown, and other
bookstores.
Whalewatching Grows Around the World
According
to a new report from the Whale & Dolphin Conservation Society
(Bath, United Kingdom), 50 independent countries and 15 overseas
territories or dependencies, including Antarctica, have at least
some level of commercial whale watching. The United States leads
the field with 3,600,000 whale watchers recorded in 1994, up from
3,243,025 in 1991. Based on these numbers and local estimates,
the Stellwagen Bank/Jeffreys Ledge area probably attracts about
11% of the total U.S. whalewatching public. Worldwide, the number
of whale watchers stands at 5,425,506. Erich Hoyt, the report's
author, notes that several communities have been transformed by
whale watching with substantial economic, educational, and/or
scientific impacts, including: Provincetown, Mass., U.S.A.; Friday
Harbor, Washington, U.S.A.; Lahaina, Hawaii, U.S.A.; Ogata, Japan;
Andenes, Norway; and Dingle, Ireland. Although whale watching
seems to be leveling off in the United States, Hoyt reports that
the five highest rates of increase between 1991 and 1994 were:
Brazil, Spain, Japan, Argentina, and New Zealand.
Education
Digest
MIMIFest
Comes to Plymouth
For
anyone who has used the curriculum or has seen the series of videos
on public television, the Voyage of the MIMI is a memorable experience.
In May, the Sanctuary sponsored the first annual MIMIFest in Plymouth
-- bringing the MIMI -- an actual 72-foot sailing ketch -- to
the State Pier while hosting four days of activities. Over 1,400
students got to tour the ship, meet Peter Marston (aka Captain
Granville), take a harbor cruise, and participate in marine studies
workshops. Scrimshaw, knot-tying and net-mending (and its relationship
to fisheries issues), a planetarium show on celestial navigation,
identification of the whales of Stellwagen Bank, and weather forecasting
rounded out the program. A teacher's conference led off the week's
activities on May 22. The Sanctuary intends to host an expanded
MIMIFest next year.
Northward
Ho! or Following the Great Whales on the Internet
From
Groundhog's Day through June 1, the Stellwagen Bank National Marine
Sanctuary served as one of the contact points for an innovative
education program that followed the northward advance of spring
and migrations of various species. The Journey North program,
based in Minneapolis, Minnesota, looked at leaf-out (the first
buds of spring) and ice-out (the last signs of ice on once-frozen
lakes) as well as the spring migrations of monarch butterflies,
northern orioles, american robins, common loons, caribou, peregrine
falcons, bald eagles, leatherback turtles, humpback whales and
northern right whales. For some of these species, students e-mailed
in sighting reports; for other species, not as easily located,
experts provided the tracking reports. The Sanctuary prepared
a weekly log on whale sightings along the east coast from a network
of whale researchers, whale watch operators, and government agency
whale specialists from as far south as the Dominican Republic
to as far north as Newfoundland. The Sanctuary also provided background
information on whale biology and behavior, as well as whale information
from other Sanctuaries in the national system. The Sanctuary is
planning to continue participating in the Journey North program
next spring. For more information, contact the Sanctuary or the
Journey North program at 125 North First Street, Minneapolis,
MN 55401; (612) 339-6959; e-mail jnorth@jriver.com.
Student-Produced Video Highlights Sanctuary
A
graduate student from Emerson College has prepared an outstanding
20-minute video about the Stellwagen Bank National Marine Sanctuary
as her master's thesis project. Amy Young, majoring in television
production, co-wrote, co-produced, and directed the show which
details the geological history of the Bank, the Sanctuary designation
process , and the on-going work of the Sanctuary staff and associated
researchers. Creative Resources Group of Plymouth donated narration,
music and audio services; while videotape footage was donated
by Robert Brown of Passage Productions, Inc., National Undersea
Research Center at Avery Point, Woods Hole Oceanographic Institution,
and Associated Scientists of Woods Hole. Plans call for distributing
the videotape to libraries, schools, exhibit centers, and other
education outlets.
Stellwagen
and the Aquanauts
GOING
DOWN! They are diving in submersibles to the Bank, studying its
wealth of resources with remotely-operated vehicles, and listening
to its sounds with sonar equipment. No these aren't research scientists
from marine research institutions -- these are high school students
from Massachusetts, Rhode Island, and Connecticut who are participating
in the Aquanaut program of the National Undersea Research Center
at the University of Connecticut, Avery Point. The students will
travel to Stellwagen Bank to pursue studies in benthic (sea bottom)
biology, ocean acoustics -- impacts of low frequency noise on
whales -- and other topics. After completing the data gathering
cruises, the students will analyze their information and write
research papers which they will present in the fall. For more
information on this project, contact the Sanctuary or the National
Undersea Research Center at (203) 445-3483.
Massachusetts-Georgia
Link for Education
What
do Massachusetts and Georgia have in common? They both have named
the northern right whale as their state marine mammal. They both
also have National Marine Sanctuaries offshore -- Gray's Reef
off Savannah and Stellwagen Bank at the mouth of Massachusetts
Bay. The two Sanctuaries are collaborating on a right whale education
package that will include an oversize poster and workbook that
details the history of the whale and whaling, anatomy and physiology,
behavior and migration, and conservation efforts. In addition,
the Sanctuaries are jointly funding the production of a 20-minute
video by the Georgia Department of Natural Resources which will
include amazing film footage of right whale mating behavior in
the Bay of Fundy, the right whales summer feeding and breeding
ground. Right whales spend the spring in Cape Cod Bay and sections
of Stellwagen Bank and pregnant females travel to the shallow
waters off the Georgia and northern Florida coast for calving.
For more information on the educators package, contact the Sanctuaries
this fall.
Research
Reports
Who's
Who and What's What Among Sanctuary Invertebrates?
In
an effort to better understand what types of prey groundfish are
seeking, and to understand the effects of trawling on these animals,
Dr. Les Watling and a team from the University of Maine will study
the marine life of the Sanctuary's seafloor this summer. Based
on images from remotely operated vehicles and side-scan sonar,
the research team has selected five different habitat types for
study. Using an apparatus called the Smith-McIntyre grab sampler,
the researchers will identify and count the invertebrates (animals
without backbones such as worms, clams, sand dollars, etc.) found
in the sand, mud, or gravel. At least five "grabs" will be done
for each site. This small project will form the basis of a larger
and longer-term (3-year) project already funded by Maine Sea Grant
which is scheduled to start in February 1996. That study is designed
to assess the effects of trawling on bottom communities and to
investigate patterns of benthic (seafloor) habitat recovery following
the end of trawling.
Tiny
Creatures with Big Roles
For
the great circle of life in the Sanctuary, the little creatures
on the sea floor and in the water column play important roles.
A researcher from the University of North Carolina at Wilmington
is looking at links between benthic microalgae (small single-celled
plants living on the seafloor) and dermersal zooplankton (free-floating
animals, such as shrimp-like copepods and krill). These organisms
are an important part of the marine food chain -- zooplankton
eat the algae, and fish, birds, and whales eat the zooplankton.
Dr. Lawrence Cahoon and his team want to determine if there are
differences in the types and amounts of algae and zooplankton
in dragged versus protected areas. Studies during the summer of
1995 will include placement of demersal zooplankton traps and
a benthic microalgal lander (for measuring oxygen exchange --
a good indicator or the amount of photosynthetic material). If
available, a remotely-operated vehicle will also be used for sampling.
Understanding
Fish Habitats
What
roles do different types of sea floors have on the numbers and
types of fish that live there? A research program proposed by
the National Undersea Research Center at the University of Connecticut,
Avery Point will begin to clarify those roles. Some examples of
habitat features associated with mobile fauna (such as fish, crustacea,
and bivalves) include: skates, crabs and hermit crabs with coarse
sand deposits on top of the Bank; snake blenny , alligatorfish,
sculpin, and ocean pout with sand-silt areas along the southwestern
flank; juvenile cod and scallops in areas of sand waves and shell
deposits. The goal of Peter Auster and his team is to develop
a better picture of the role that landscape features play on the
distribution of organisms. Through this process, scientists can
better understand if particular areas serve as nursery, breeding,
or feeding grounds for commercially important species. By better
understanding who lives where and when, marine resource managers
can better protect exploited species at critical points in their
life cycles.
Getting
to the Bottom of Things
The
geological history of Stellwagen Bank is relatively simple --
it was created (as was Cape Cod) by the last great ice sheet that
deposited sand and gravel during its northward retreat. In geological
terms this happened only recently, about 18,000 years ago. But
what of the underlying bedrock. Dr. Robert Oldale of the U.S.
Geological Survey reports that these rock formations may have
a history that spans more than 500 million years. A 1994 study
using seismic soundings showed that the deepest rock below the
bank resembles bedrock exposed at the surface in eastern Massachusetts
(which ranges in age from 570 million years old when there was
little life on earth to 150 million years when dinosaurs roamed).
Between the bedrock and the glacial deposits, scientists have
recorded rock layers that resemble the strata under the coastal
plain of New Jersey (ranging in age from 140 to 5 million years).
These sedimentary deposits were eroded by rivers and streams,
beginning the process that would shape the present bank. Successive
glaciers, in their turn, swept away most of the coastal plain
deposits, leaving behind only remnants of sedimentary rock and
carved basins in the bedrock. The retreat of the Laurentide Ice
Sheet of the last ice age created the bank that we know today.
Sanctuary
Research Plan in Development
On
April 6, 1994, over 60 scientists and resource managers from across
New England came together in Plymouth to assist the Sanctuary
in identifying specific scientific research projects the Sanctuary
should encourage, support, and facilitate over the next five years.
The workshop, organized by Peter Auster and Ivar Babb of NOAA's
National Undersea Research Center at the University of Connnecticut,
with logistical support provided by the Urban Harbors Institute
at the University of Massachusetts at Boston, focused on three
broad research categories: baseline studies to determine features
and processes of the environment, including abundance, distribution,
and interactions among living marine resources and patterns of
human activities; monitoring studies to document changes in ecological
processes and patterns, environmental quality, and human activities;
and, predictive studies to assess causes and effects of ecological
and environmental changes. A summary document details the workshop
recommendations which cover a broad spectrum of issues, all focused
on providing information to enhance the effective management of
Sanctuary resources. The document is being used as the basis for
the Sanctuary's formal research plan, which will ultimately be
incorporated into the Sanctuary management plan. Copies of the
Workshop Summary are available from the Sanctuary office.
Special
Report Prepared for the New England Fishery Management Council
The
New England Fishery Management Council (NEFMC), seeking innovative
management strategies, and attempting to effectively address the
burgeoning interest in activities such as mariculture, is developing
policies to guide them in identifying and designating "special
management areas" or SMAs. While regional fisheries management
councils have had this authority for years under the Magnuson
Act (the federal statute focused on fishery management), only
recently have they begun to identify potential uses for SMA designations.
To assist the New England Council in developing its SMA policies,
the Sanctuary has prepared a special report, delivered to the
Council in January 1995, entitiled "Use of Special Management
Areas by Fishery Management Councils: Examples and a Case Study."
As the title suggests, the report details examples of the use
of the SMA designations by regional councils, with a focus on
the groundbreaking work of the South Atlantic Council in an area
known as Oculina Bank off northern Florida. Copies of the report
are available from the Sanctuary office.
A
second special report is currently in preparation which will make
recommendations regarding the process by which SMA designations
are made. The report focuses on guidelines for submission of proposals,
possible decisionmaking criteria, and some observations on implementation
and oversight of designated areas.
Left
Turn or Right
Was
it right at the bank and left at the river? Or vice versa? For
some whales, those long distance migrations don't always go as
smoothly as Mother Nature planned.
On
December 3, 1994, a right whale was spotted off Penns Landing,
Philadelphia in the Delaware River -- some 80 miles from the ocean
(it eventually reached 100 miles upriver). The animal seemed disoriented
and was bumping into vessels with audible thuds which produced
bloody wounds on its head. Researchers thought the animal might
be entangled in debris since it was swimming at an unusual angle.
However, after more study, the rescue crew decided that the animal
was not entangled.
The
team then tried to guide the whale out of the river by playing
female right whale sounds to attract it and killer whale sounds
to scare it (killer whales or orcas prey on young right whales).
The would-be rescuers had nets ready to capture the whale if that
option became necessary. In the end, the whale swam out of Delaware
Bay on December 10th and continued on out into the ocean.
The
rescuers determined that the whale was a juvenile male and named
him Shackleton after Sir Ernest Shackleton, a not-so-very successful
Antarctic explorer who survived ten danger-filled months on the
Antarctic ice without a ship before leading all his men to safety.
It was felt that Shackleton the whale had also encountered his
greatest hardship and survived. Although Shackleton may have suffered
some damage during his sojourn up the river (he was hit by at
least one boat -- a tug), the researchers hope to see him in the
Bay of Fundy this summer or perhaps Stellwagen Bank next spring.
Although he wasn't seen in Cape Cod Bay this year, scientists
were not surprised. The whale's older sibling, born in 1990, was
not seen for four years after its birth -- so Shackleton may just
be following family tradition. That earlier sibling and Shackleton's
mother had also been seen near Delaware Bay, so the area may be
a sort of landmark for this family. Perhaps Shackleton just wasn't
paying attention when his Mom showed him the route the first time.

Group, New England Aquarium.
