“Delving into the origins of tropical marine biodiversity” from University of Hawaiʻi at Mānoa
New research shows that marine animals in Hawaii are not as isolated as scientists previously thought. Instead, research shows that these animals are “radiating back across the ocean” and adapting to new environments.
“EU tightens ban on shark finning” from BBC
The practice of shark finning has been illegal in the EU since 2003, but a loophole allowed fishing crews to remove fins from shark carcasses. Now, ministers have agreed to close that loophole in an effort to strengthen the shark finning ban.
New research shows that fish with radioactivity from the Fukushima Dai-ichi powerplants pose little risk to the fish and the humans that eat them. The research shows that the amount of radiation in contaminated fish is comparable to or less than the dosages associated with other common foods, air travel and other background sources.
“North Sea cod stocks ‘on road to sustainability‘” from BBC
According to Marine Stewardship Council (MSC) research, North Sea cod stocks are “on the road to sustainability.” MSC says it is too soon to tell when the fishery will be designated as sustainable, but it is likely to be ready within years, not decades.
“Pop quiz: Can you find the rip current?” from CA Sea Grant
Last week was Rip Current Awareness Week. Check out this post to see what you learned during the week!
Researchers found that fish can hide in the open ocean by changing the way light reflects off their skin. This technique is incredibly effective and could be used to develop new camouflage materials for use in the ocean.
“Seals reveal secrets of polar oceans” from Planet Earth Online
It is challenging to collect data from the Polar seas and as a result, their role in climate and weather systems is poorly understood. Now, scientists are using seals fitted with special tags to collect temperature and salinity measurements from polar oceans. The data is being used by weather forecasters, climate scientists and biologists.
“Stopping Illegally Caught Fish at the Dock” from Pew Environment
Check out this post to learn about the Agreement on Port State Measures to Prevent, Deter and Eliminated Illegal, Unreported and Unregulated Fishing, or the Port State Measures Agreement (PSMA). The PSMA is designed to eliminate IUU fishing and report illegal fishing vessels in order to keep IUU fish out of the world’s markets.
“Stranded orcas hold critical clues for scientists” from UC Davis
A new study from UC Davis shows that the development of a standardized killer whale necropsy system has increased the amount of data collected from stranded orcas from two percent to 33 percent. Orca strandings are not that common so it is critical for scientists to learn as much as they can from these unfortunate incidences and this standardized necropsy system is proving to be an effective way to do so.
A new report identified the most dangerous waters for shipping and found that accidents put some of the most ecologically important areas in danger. The worst “accident hotspots” are in the South China, Mediterranean and North Seas.
Whale and Dolphin Conservation recently released a study showing the non-economic benefits of whale watching. The results show that going on a whale watching tour can increase the watcher’s awareness about the ocean’s vulnerability and can inspire them to change their attitude and actions regarding conservation.
“The Right Rules for Keeping Ships from Hitting Right Whales” from NY Times
NOAA would like to extend the rules implemented five years ago to limit collisions between ships and endangered North Atlantic right whales along the East Coast. NOAA states that the existing rules have reduced the number of whales struck every year since the rules went into effect in 2008.
