Ocearch Launches 41st White Shark Research Expedition
and health of the white shark in the Northwest Atlantic Ocean. The company said it was headed back to the area where they first began their Northwest Atlantic White Shark Study nine years ago, off the coast of Massachusetts. The area of work is being expanded to reach a new part of the Northeast US, the waters off of New Hampshire."We know the area around Cape Cod and Nantucket Island is a summer aggregation site for the white shark. But not all white sharks in the Northwest Atlantic spend their summers off Cape Cod. "A large component migrates as far north as Newfoundland

treatment from one day to the next, despite their super strong initial reactions. That kind of diminishing physiological or behavioral response to a noise may increase squids’ susceptibility to predators.”In the next decade, the offshore wind industry is expected to expand rapidly in the Northeast U.S., causing concern among federal entities and commercial fishermen over how the behavior of commercially important fish and other species will be impacted.Squid play a key role in the marine food web. Many marine mammals, seabirds, and fish feed off squid, as well as humans, who eat about three

are also relying on the use of a remotely operated vehicle (ROV) to periodically survey the nets. The ROV takes real-time video snapshots of activity below the surface to supplement the top-mounted cameras.“This is the first time anyone has captured video of active sink-gillnet fishing in the northeast U.S. that we know of,” said Owen Nichols, director of Marine Fisheries Research for CCS. He says that assessing and documenting depredation by seals and other marine animals is often done by human observation on deck. “In general, we don’t know much about what goes on around the
Currents Not Linked to New England Sea Level
There is no direct link between major North Atlantic ocean currents and sea level along the coast of northeastern United States, according to a recent study by the Woods Hole Oceanographic Institution (WHOI).The study, published last week in the journal Geophysical Research Letters, examined both the strength of the Atlantic Meridional Overturning Circulation (AMOC)—a conveyor belt of currents that move warmer waters north and cooler waters south in the Atlantic—and historical records of sea level in coastal New England.“Scientists had previously noticed that if the AMOC is stronger
McLane IFCB Helps in Rust Tide Study
Grant for their project, “Reducing risk for shellfish farmers through real-time, automated, harmful algal bloom monitoring and mitigation.”Dr. Ward said: “Annual blooms of rust tide have increased spatially and temporally in areas of shellfish aquaculture production throughout the northeast US. Utilizing the IFCB in this project will allow us to get warnings and real-time information out to the farmers in the region, so that the farmers can avoid economic losses and continue to produce high-quality seafood."The dinoflagellate C. polykrikoides is a leading cause of HAB-associated

Deep-sea Canyons and Seeps Discovered Off U.S. Northeast
Ocean explorers in July on NOAA Ship Okeanos Explorer discovered a wide diversity of seafloor features and communities of life in the largely unexplored deep-sea canyons off the northeast U.S. coast. Now through August 16, as the expedition continues, the public can join the mission as "citizen scientists," at oceanexplorer.noaa.gov/okeanos, to see live seafloor video and listen as scientists discuss their observations in real time. During the expedition's July leg, there were nearly 60,000 visits to the live streaming video. Canyons represent some of the most striking features of the
