Join members of the all-volunteer Bayshore Watershed Council on Sunday, June 11, 2017 for Seine the Bay Day along Raritan Bay & Sandy Hook Bay in New Jersey!
You are invited to help us. Bring a friend or bring your family. The event is free!
Seine the Bay Day is an annual early summer event. Volunteers will help drag a long net (called a seine net) through the water to find out what might live in the shallow part of the bay. The catch is never the same; we may catch juvenile fish, shrimp, or even baby puffers or seahorses in the net. It should be a fun day.
Times and locations can be found below. Rain or strong winds will cancel the event.
Seining team members will be citizen scientists. All fishes, crabs, and other aquatic creatures will be identified, measured, and cataloged; and returned to the water.
In addition, watershed members will collect water temperature and turbidity information; and document the tidal stage, and note the aquatic vegetation in the area.
We will conduct this early summer seining survey at four (4) sites along Raritan Bay & Sandy Hook Bay. Below are locations & times. High tide is around 10:00am.

Marine Species Distribution Shifts Will Continue Under Ocean Warming
Changes impact local fishing communities, resource management
Scientists using a high-resolution global climate model and historical observations of species distributions on the Northeast U.S. Shelf have found that commercially important species will continue to shift their distribution as ocean waters warm two to three times faster than the global average through the end of this century. Projected increases in surface to bottom waters of 6.6 to 9 degrees F (3.7 to 5.0 degrees Celsius) from current conditions are expected.
The findings, reported in Progress in Oceanography, suggest ocean temperature will continue to play a major role in where commercially important species will find suitable habitat. Sea surface temperatures in the Gulf of Maine have warmed faster than 99 percent of the global ocean over the past decade. Northward shifts of many species are already happening, with major changes expected in the complex of species occurring in different regions on the shelf, and shifts from one management jurisdiction to another. These changes will directly affect fishing communities, as species now landed at those ports move out of range, and new species move in.
“Species that are currently found in the Mid-Atlantic Bight and on Georges Bank may have enough suitable habitat in the future because they can shift northward as temperatures increase,” said lead author Kristin Kleisner, formerly of the Northeast Fisheries Science Center (NEFSC)‘s Ecosystems Dynamics and Assessment Branch and now a senior scientist at the Environmental Defense Fund. ”Species concentrated in the Gulf of Maine, where species have shifted to deeper water rather than northward, may be more likely to experience a significant decline in suitable habitat and move out of the region altogether.”
President of France, Emmanuel Macron, denounces Trump for WITHDRAWAL of Paris Climate Accord Agreement on 6/1/2017 - its NOT RENEGOTIABLE
The leaders of France, Germany and Italy released a joint statement saying the Paris agreement on global climate change was “irreversible” and constituted “a vital instrument for our planet, societies and economies.
"This will be the day that the United States resigned as the leader of the free world....Donald Trump’s decision to withdraw the US from the Paris Agreement on climate change means the US is no longer the leader of the free world....The irresponsibility of this act is breath-taking, because the Paris climate accords are actually extraordinarily flexible. They do not dilute American sovereignty. They allow every country to make its own plans. That’s why countries that have jealously guarded their sovereignty – like China, like Iran, like Russia – have all signed on." - CNN’s Fareed Zakaria
"It is absurd and dangerous for the president of the most powerful nation on earth to reject science.” - U.S. Senator Bernie Sanders
How another dead whale ended up in the waters off Jersey City

A dead whale that found in the waters of Port Newark this week is currently tethered to a mooring near Port Liberte in Jersey City, the Army Corps of Engineers said.
The whale, which is estimated to measure 45 feet in length and weigh 40 tons, was found early Tuesday morning on the bow of a ship in Port Newark, said Michael Embrich, a spokesman for the Army Corps of Engineers.
The mammal was brought to the waters just off Jersey City and will eventually be towed out to sea, weighted down and sunk to the ocean floor to prevent it from becoming a further hazard to navigation, the spokesman added.
Bob Schoelkopf, the founding director of the Marine Mammal Stranding Center in Brigantine, said the whale was likely struck by a freighter at sea and dragged to Port Newark. It did not swim into local waters, he said.
"Whether the animal was alive or not when it was struck we can't tell," Schoelkopf said. "The animal, when they are struck by freighters, the freighters have no clue, they're so big they don't know they hit them."
Clockwise from the upper left corner: Cliff Swallow, Bank Swallow, Purple Martin, Tree Swallow, and Barn Swallow.
Swallows are small, speedy, short-winged aerial hunters with slender bodies and pointed wings and a tail, just like a jet airplane. The birds are quick and graceful in flight, often catching a variety of flying insects in midair during a long, dizzying air travel pattern near the water or in a meadow.
These short-billed aerial hunters know exactly what they are doing. A single Barn swallow, for example, can consume 60 insects per hour, an amazing 850 per day. The small birds are surely one of Mother Nature’s most successful avian insect predators.
They are not lazy birds either. Swallows can fly several miles from their nest site to forage for not only insects, but in some cases for spiders, snails, seeds and berries too.
A quick glance during sunset and you might think the birds were bats. The quick aerial feeding lifestyle of a swallow gives it some resemblance to a Little Brown Bat. Both hunt for insects and can dart quickly through the air, abruptly changing directions on the wing to catch a mosquito, fly, bee, or winged ant.
But as Dr. David W. Winkler, a professor and curator of birds at Cornell, points out in a July 16, 2002 interview in The New York Times there is a big difference in the way swallows and bats forage for food. “Swallows are definitely visual foragers,” and “hunt only until dark, when the bats take over.” While echolocation is used by bats to catch prey, Dr. Winkler goes on to explain that swallows have ultraviolet light vision. This helps the birds find insects, including moths and butterflies, which have body coatings that strongly reflect UV light. Their eyes could also be polarized to help spot an insect from long distances. With these important tools, “swallows can come back to the nest with up to 50 live insects in their mouths.”
Male & Female Purple Martins
One would think the birds are the best free, nontoxic pest control in the world. Yet, they cannot do it alone. With millions or billions of insects hatching out of eggs each summer, and with only a limited number of swallows in any one area, the birds can only really play a small role in mosquito population reduction. But this only means we need to increase the amount of nesting boxes, habitat and homes to expand the swallow population.
The edge of an estuary can be full of surprises, some not always scenic.
A dead dolphin washed ashore early Wednesday morning along the southern shore of New York Harbor, in Port Monmouth, NJ. The dolphin’s body had been badly decomposed suggesting it had passed away some time ago.
The approximately five-foot long dolphin was perhaps a sub-adult or in human terms – a teenager. Adult males range in size from about 8 to 13 feet, and adult females range in size from about 7 to 12 feet.
The cause of death is unknown, but there are sadly many modern-day threats to end the life of a Bottlenose dolphin. According to the World Wildlife Foundation, whales and dolphins continue to be threatened by:
There is also evidence to suggest that chemcial pollution is weakening the immune systems of marine mammals. Persistent Organic Pollutants (POPs) including pesticides such as DDT, and industrial chemicals; most famously the Polychlorinated biphenyls (PCBs) are a major hazard. PCBs are linked to immune system suppression and reproductive failure. In New York Harbor and surrounding waters, we are still sadly living with a legacy of polluted water.
Staff at the NJ Marine Mammal Stranding Center were notified of the dead dolphin in Port Monmouth. If you see a marine mammal that appears dead, injured, entangled, sick, or being harassed by a person, in New Jersey call the Marine Mammal Stranding Center at 609-266-0538.
