Week in Review: Studying Shark's Social Lives to Expose Their Friendly Side and More!

1. Studying Shark's Social Lives to Expose Their Friendly Side

A study began a year ago to investigate if sharks engage in the same kind of social behaviors as humans. The research, conducted by a team at the Behavior, Ecology and Evolution of Fishes Laboratory at Macquaire University, was collected over a three month period of time at Jervis bay, on the New South Wales coast of Australia. The subject of the study were 250 Port Jackson sharks. The sharks were tagged with passive integrated transponders (PIT) and acoustic tags. The study continues to develop to collect more data and compile conclusions.  Read more...


2. Greenhouse Gas Can Escape the Deep Ocean in Surprising Way

This week, an article was published in Marine Chemistry and reports that carbon dioxide can emerge from the deep ocean in a surprising way. The research team was comprised of scientists from Mote Marine Laboratory, Georgia Institute of Technology, and the Laboratorie de Sciences du Climat et de l'Environnement in France. The study focused on the organic matter deposits that can be found as deep as 16,400 feet in the ocean. Bacteria feed on this muck and release carbon dioxide. The new finding in this process is that bacteria use metal ions to release carbon dioxide. Read more...


3. Jason Ocean Height Mission Blasts Off 

Jason-3, a US-European satellite, was launched this week. This satellite will be used to track currents, tides, winds, wave heights, and storms.The goal of this mission is to create a data set on sea level rise to an accuracy of better than 4cm. The satellite will provide detail into the elevation of the ocean surface. This information provides scientists with information on the temperature, salinity, and current direction and speed.   Read more...


4. Ten Years After the Thames Whale, How Are Britain's Sea Mammals Faring?

The British Isles are home or visited by 29 species of whales, porpoises, dolphins, and sever species of seals in its waters. A good example of one of those visitors was the northern bottlenose whale who swam up the River Thames in front of the Houses of Parliament.  A few days after the first sighting, the whale died from a combination of dehydration, physiological stress, cardiovascular collapse and organ failure. An article written on The Conversation discusses the state of the British marine mammals and the impacts that climate change and human activities have made on the species.  Read more...


5. Robot Subs Inform Protection of English Deep-Sea Corals

Robot subs inform protection of English deep-sea coralsScientists at the National Ocean Centre (NOC), head-quartered in Shouthampton, England, used data collected from a variety of marine robots to develop conclusions on how to improve the management of cold-water coral reefs. The team was able to map and image steep and overhanging rock walls that hosted extensive coral communities. Previously, those areas were over looked by ship-based instruments.  Read more...


6. More Plastic Than Fish in the Sea by 2050 

Plastics in the sea, today and in 2050For years there have been articles on the huge impact that plastic pollution has on the ocean. This week, the Ellen MacArther Foundation released a report entitled "The New Plastics Economy: Rethinking the Future of Plastics". The report reveals that plastics production has increase twentyfold since 1964 and is expected to quadruple by 2050. According to the foundation's research, " at least 8m tonnes of plastics leak into the ocean- which is equivalent to dumping the contents of one garbage truck into the ocean every minute". By 2025, the ocean is expected to contain one tonne of plastic for every three tonnes of fish, and by 2050, more plastics will be in the ocean than fish. To read the detailed report, click here...
