More than 1,400 dolphins slaughtered in one day in Faroe Islands – “Possibly the largest single hunt of cetaceans ever recorded worldwide”

By Joshua Nevett 14 September 2021 (BBC News) – The practice of dolphin hunting in the Faroe Islands has come under scrutiny after more than 1,400 of the mammals were killed in what was believed to be a record catch. The pod of white-sided dolphins was driven into the largest fjord in the North Atlantic […]

A Florida manatee has the word “Trump” carved in its back, causing serious scarring. The U.S. Fish and Wildlife Service is investigating the harassment of this manatee. The animal was reported to federal authorities over the weekend of 9 January 2021. The animal was reported swimming in the Blue Hole, the headwaters of the Homosassa River. The USFWS is looking for any information regarding the harassment of this animal. Call the Florida Fish and Wildlife Conservation hotline at 888-404-3922 to report information.

Someone carved “Trump” on a Florida manatee, causing serious scarring – “This abhorrent action goes beyond the bounds of what is considered cruel and inhumane”

By Johnny Diaz 11 January 2021 (The New York Times) – The sighting in Florida this week of a manatee with “Trump” in block letters on its back has prompted an investigation and a plea for help from a nonprofit conservation group. The Center for Biological Diversity said it was offering a $5,000 reward for […]

10 years after BP spill: Oil drilled deeper; rules relaxed – “I’m concerned that in the industry, the lessons aren’t fully learned — that we’re tending to backslide”

By Kevin Mcgill and Matthew Brown 18 April 2020 NEW ORLEANS (AP) – Ten years after an oil rig explosion killed 11 workers and unleashed an environmental nightmare in the Gulf of Mexico, companies are drilling into deeper and deeper waters, where the payoffs can be huge but the risks are greater than ever. Industry leaders and […]

Spatial cumulative extents of the Deepwater Horizon (DWH) oil spill. (A) Cumulative NESDIS anomaly daily composites integrated from 20 April 2010 to 21 July 2010. Daily fishing closures are marked with gray lines; the cumulative fishing closure area is marked with a thick dashed yellow line. The black star represents the location of the DWH blowout. (B) Cumulative value of daily average oil concentrations (ppb), integrated across the same time span as (A) and across water depths. Vertical depth layers are 0 to 1 m, 1 to 20 m, and in 20-m increments down to 2500 m. Sediment and water samples with higher-than-background concentration are marked in bright green and dark blue circles, respectively. Red crosses in (B) represent approximate locations of DWH-related oil detections reported in previous studies. Daily fishery closures are marked with black polygons; the cumulative fishery closure area is marked with a dashed thick polygon. AB, Apalachee Bay; DP, Deep Plume; EFS, East Florida Shelf; FK, Florida Keys; LC, Loop Current System; TXS, Texas Shores; WFS, West Florida Shelf. (C) Categorization of the modeled oil spill are as follows: (i) nontoxic, PAH concentrations above background level and smaller than 0.5 and 1 ppb at the surface (depth, 0 to 1 m) and in the water column (depth, >1 m), respectively; (ii) toxic-to-biota and invisible, PAH concentrations 0.5 to 17 ppb at the surface and above 1 ppb in the water column; and (iii) toxic and visible, PAH concentrations above 17 ppb. In (C), categories were computed according to maximal concentrations across time. (D) Duration of toxic concentrations across the domain. (E) LC50 of 12 experiments examining the photoinduced toxicity to blue crab (31), fiddler crab (33), mahi mahi (29, 30), red drum (32), and speckled sea trout (32) (for more details, see table S2). (F) The spatial extent of the toxic concentrations from (E); color codes in (F) are according to bar colors in (E), representing concentrations exceeding LC50. In (F), toxic PAH of 0.5 ppb was concentrations were considered for surface waters only (depth, 0 to 1 m). Graphic: Berenshtein, et al., 2020 / Science Advances

The toxic reach of the Deepwater Horizon oil spill was much larger and deadlier than previous estimates – “Large areas of the Gulf of Mexico were exposed to invisible and toxic oil that extended beyond the boundaries of the satellite footprint and the fishery closures”

By Darryl Fears 12 February 2020 (The Washington Post) – The spread of oil from the Deepwater Horizon disaster in the Gulf of Mexico was far worse than previously believed, new research has found. As the worst offshore oil spill in U.S. history approaches its 10th anniversary in April, a study by two University of Miami researchers […]

In 2019, 214 grey whales washed up dead on the West Coast of North America – “They get eaten alive”

By Lisa Johnson 28 December 2019 (CBC News) – The first grey whale found dead in B.C. last year was in such rough shape that someone called to report it was tangled up in a big pink buoy. The pink wasn’t plastic, officials learned when they arrived to tow the skinny male to shore near […]

(a) Estimated distances animals can travel during the Phocine distemper virus (PDV) latent and infectious period (1 week, 2 weeks, and 4 weeks) illustrating the areas where viral transmission could occur, based on median travel speeds calculated for satellite-tagged bearded seals (green circles), spotted seals (orange), Steller sea lions (blue), and northern fur seals (purple). (b) Recorded tracks of a PDV seropositive bearded seal followed in July 2009 and a seropositive northern fur seal followed in November 2010 shown with sympatric PCR positive spotted seals, ribbon seals, and northern fur seals sampled 2009–2010. Sea ice is shown at its minimum extent in September (panel a) and retreating the following July after reaching a maximum winter extent (panel b).

Deadly virus spreads among marine mammals as Arctic sea ice melts – Scientists fear the virus, once found only in European waters, could spread to the U.S. West Coast

By Sarah Gibbens 7 November 2019 (National Geographic) – When sea otters in Alaska were diagnosed with phocine distemper virus (PDV) in 2004, scientists were confused. The pathogen in the Morbillivirus genus that contains viruses like measles had then only been found in Europe and on the eastern coast of North America. “We didn’t understand how a […]
