Glacier depth affects plankton blooms off Greenland

Tue, 14 Aug 2018 10:14:38 EDT ~ The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean. Find out more...

Young salmon may leap to 'oust the louse'

Mon, 13 Aug 2018 10:03:03 EDT ~ A study by aquatic ecologists reveals that young salmon may jump out of water to remove sea lice. Find out more...

Sea stars critical to kelp forest resilience

Mon, 13 Aug 2018 10:03:00 EDT ~ A study by a resource and environmental management researcher reveals that sunflower sea stars play a critical role in the resilience of B.C.'s kelp forests, which are among the most productive ecosystems on Earth. Similar to land-based forests, kelp forests provide essential habitat for species and also help remove CO2 from the atmosphere. Find out more...

Marine mammals lack functional gene to defend against popular pesticide

Thu, 09 Aug 2018 14:12:15 EDT ~ As marine mammals evolved to make water their primary habitat, they lost the ability to make a protein that defends humans and other land-dwelling mammals from the neurotoxic effects of a popular human-made pesticide. The implications of this discovery led researchers to call for monitoring our waterways to learn more about the impact of pesticides and agricultural run-off on marine mammals, such as dolphins, manatees, seals and whales.

Diverse symbionts of reef corals have endured since 'age of dinosaurs'

Thu, 09 Aug 2018 14:11:55 EDT ~ Coral-algal partnerships have endured numerous climate change events in their long history, and at least some are likely to survive modern-day global warming as well, suggests an international team of scientists. Find out more...

'Biological passport' to monitor Earth's largest fish

Thu, 09 Aug 2018 09:34:35 EDT ~ Whale sharks, the world's largest fish, roam less than previously thought. This new study used stable isotope analysis to demonstrate that whale sharks feeding at three disparate sites in the Western Indian Ocean and Arabian Gulf rarely swim more than a few hundred kilometers north or south from these areas according to researchers. Find out more...

Effective method to control algae growth on Hawaiian coral reefs

Wed, 08 Aug 2018 19:36:38 EDT ~ Researchers have found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i. Find out more...

Models may help reduce bycatch from longline fishing

Wed, 08 Aug 2018 15:34:05 EDT ~ Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after becoming snagged or entangled in longline fishing gear. New models may help reduce the threat by giving regulatory agencies a new tool to predict the month-by-month movements of longline fleets on the high seas and determine where and when by-catch risks are greatest.

New species of rare ancient 'worm' discovered in fossil hotspot

Wed, 08 Aug 2018 13:42:28 EDT ~ Scientists have discovered a new species of lobopodian, an ancient relative of modern-day velvet worms, in 430 million-years-old Silurian rocks in Herefordshire, UK. Find out more...

Expedition probes ocean's smallest organisms for climate answers

Wed, 08 Aug 2018 13:41:54 EDT ~ In August a team of scientists is sailing 200 miles to the northeastern Pacific Ocean with advanced robotics and other instruments on a month-long quest to investigate plankton and their impact on the carbon cycle. Find out more...
