Night  Patrol Examines Wrack Line Discovery

The most awe-inspiring, the most beautiful, the most powerful and the most dangerous aspect of sea turtle rescues is the night patrol, when gentle dunes are transformed by shadow and wind and tide into a dream-like world of surreal shapes and psychedelic colors.  Daytime familiar vanishes; nighttime mystery appears.  As westerly gales toss breakers against the beach, sound itself is altered and dominated by rumbles and crashes and whistles that flood the air.

 Don Lewis Opens Channeled Whelk Egg Casing

Friday night, participants in Mass Audubon’s Stranding Weekend, which was co-led by the Turtle Journal team, headed to Duck Harbor in northwest Wellfleet for their first sea turtle patrol.  After a candlelight dinner in the Wellfleet Bay Wildlife Sanctuary, they learned about cold-stunned sea turtles and various other marine species that strand on bayside beaches in autumn.  Now they were ready for their first field action.

Shooting Stars Streaks the Night Sky

With a westerly breeze blowing inshore, Don Lewis suggested they patrol from Duck Harbor in Wellfleet to Ryder Beach in Truro, about a 1.5 mile hike.  After a day of on and off rain, the skies had cleared as the group approached the beach.  The moon was in new phase, and as only Carl Sagan could say, billions and billions of stars adorned the night sky with the Milky Way stunningly bright as it stretched from Cassiopeia (the Great “W”) in the north to Sagittarius in the south.  We stared northward above the twinkling lights of Provincetown and we were dazzled as a brilliant shooting star danced across the sky to a chorus of “ohs” and “ahs.”

1.5 Mile Night Patrol from Wellfleet to Truro

While no cold-stunned sea turtles were discovered, various critters were unmasked beneath the seaweed wrack.  Sue Wieber Nourse found a horseshoe crab molt from a juvenile specimen that offered a perfect lesson plan on this important tidal species which has contributed so much to medical research and scientific discovery, including at least one Nobel prize.  A channeled whelk casing opened another lesson as the group marched northward to the cadence of the pounding surf.

Another Shooting Star Blazed across the Night Sky

Nearly an hour later, as we gathered at Ryder Beach to review our discoveries, another magnificent shooting star exploded across the night sky as if to punctuate this unique moment we had all experienced on the darkened, windswept beaches of Outer Cape Cod.

Rescue Endangered Sea Turtles,

               Recover Marine Megafauna

                              from Storm Battered Beaches

Life on the Edge 001 480

Tiny Kemp’s Ridley Sea Turtle Rescued from Brewster Beach 

A perfect summer ends and fall brings dramatic change to Cape Cod.  Not just foliage, but the whole fabric of coastal life transforms from easy summer to harsh winter.  Summer’s gentle breezes, cerulean skies and toasty beaches are blown away by autumn storms that howl across the bay.  Summer ripples grow into towering breakers that reshape beaches and deposit oceans of treasure on the shoreline.  Buried among seaweed, flotsam and jetsam lie adventure and discovery in the form of marine creatures that are tossed ashore to helplessly succumb to the elements.  Yet, thanks to beach patrols launched by Mass Audubon’s Wellfleet Bay Wildlife Sanctuary, more than a thousand of the most endangered sea turtles in the world have been rescued from these impossible circumstances and restored back to the wild.  Countless marine mammals, giant ocean fish and amazing denizens of the sea have been recovered, yielding breakthrough discoveries chronicled in nature magazines and scientific journals.  And now you’re invited to experience this adventure first hand in Mass Audubon’s Marine Animal Stranding Weekend.

Sue Wieber Nourse Examines 11-Foot Blue Shark 

On the weekend of November 5th to 7th, Mass Audubon invites a few adventurous souls to join its crack team of coastal rescuers.  From Friday to Sunday, teams will scour beaches, day and night, from Provincetown to Sagamore in search of distressed animals.  In between high tide patrols, participants will take a bayside cruise to Billingsgate Shoal to gain a sea critter’s eye-view of the coastline, to search for pods of pre-stranding animals, and to investigate harbor and grey seal colonies, as well as overwintering seabirds and sea ducks.  Experts will reveal secrets of marine biology and coastal ecology in seminar settings and one-on-one lab work, and still have time to join participants for quiet dinner conversation about the future of the world’s oceans and their most precious species.

Sea Turtle Patrol Discovers Storm Tossed Seal

Still, the most extraordinary adventures come with midnight high tides.  In crisp November skies, stars hang like Christmas tree ornaments suspended in a shimmering Milky Way garland stretching from Sagittarius in the south to Cassiopeia’s “Big W” in the north.  Footsteps fall silently in the soft, moist sand.  The only sound comes from pounding surf that explodes in your path as a 12-foot flood tide recedes to reveal secrets left behind in the seaweed strewn wrack line.  The beam of your flashlight arcs from dune to sea and back again, searching for mysterious shapes hunkering in the dark shadows.

Upside Down Kemp’s Ridley Rescued from Cape Cod Beach

You never know what the night may reveal.  Perhaps a cold-stunned Kemp’s ridley sea turtle tossed upside down on the beach by a northwesterly gale.  Recovering this semi-tropical animal from the cold darkness before hypothermia sets in will make the difference between life and death for this turtle and may make the difference between survival and extinction for this critically endangered species.

Seven Foot Ocean Sunfish

Around another bend might lurk a giant ocean sunfish trapped on the flats by a receding tide.  This bizarre looking creature represents the largest bony fish in the ocean and can be found on Cape Cod beaches each fall.

Electric Torpedo Ray Found by Sea Turtle Patrol

For an electrifying experience, don’t discount a large torpedo ray that stuns its prey with 220 volt charge.  Ouch!  Last year brought nearly a dozen torpedo rays onto bayside beaches from Truro to Sandwich.

Nature, especially on the Outer Cape, offers no guarantee of weather or animals.  Stranding events are driven by prolonged wind conditions, dropping water temperatures and tidal flows.  Yet, early November marks the beginning of the historical stranding period.  And, no matter what has been found in the past, what is absolutely guaranteed to greet you around the next bend in the shoreline is the challenge of the unknown and the adventure of a lifetime.

Mass Audubon’s Marine Animal Stranding Weekend offers a once-in-a-lifetime experience for the adventurer deep inside you; the one who remembers so fondly those great moments of summers past and who finds the walls of boardroom, classroom, operating room, living room, corner office or office cubicle a bit too claustrophobic to endure the whole, long winter without a refreshing breath of cutting edge discovery.  Welcome to a weekend unlike anything you have ever experienced.  Welcome to the Marine Animal Stranding Weekend at the Wellfleet Bay Wildlife Sanctuary.

Battered by Storms and Waves, Outer Cape Suffers Significant Erosion

Wednesday, March 10th, 2010

Waves Rumble Ashore at Wellfleet’s Newcomb Hollow Ocean Beach

Late February and early March storms battered Outer Cape Cod causing substantial waterfront erosion on both ocean and bay sides.  Under bright sunshine on Saturday, the remnants of these storms still endured with breakers crashing along the nearly 30 mile Great Back Beach.  Enormous gouges have been ripped out of the towering Atlantic coastal sand banks.

Scalloped Erosion at South Terminus of Indian Neck Sea Wall

On the bayside, erosion has been equally destructive.  At the south edge of the Indian Neck sea wall, “scalloping” has cut deeply into the bank and now threatens the wooden stairway.  Despite supposedly protective tidal fencing, trees have been ripped from the bank by the erosive force of winter storms and flood tides.

Continuous Winter Overwash Transforms Indian Neck Salt Marsh

Nearby, this winter’s continuous overwash of the foredune along Indian Neck’s Blackfish Creek shore has transformed the salt marsh habitat previously protected behind it.

Winter Tides Threaten Terrapin Nesting Sites on Lieutenant Island’s Marsh Road 

Repeated storms and flood tides soften and threaten the extremely productive terrapin nesting sites along Marsh Road on Lieutenant Island’s south shore.  Tidal wrack has been strewn along the roadway and into abutting yards.  Turtle Journal has not previously seen such erosion in the last dozen years.

Four Additional Pilot Whale Skeletons Exposed by Tidal Erosion

On the west shore of Lieutenant Island, four more pilot whale skeletons have extruded from the sand with winter battering.  See the earlier Turtle Journal posting, Whale Bones Rise from Sands of History, from late January 2010.
