By Tim Schröder 3 August 2017(Helmholtz-Zentrum Geesthacht) – Nitrogen compounds are an important factor in the production of algal biomass. The team led by biologist Kirstin Dähnke from the Institute of Coastal Research at the Helmholtz-Zentrum Geesthacht has been carrying out extensive Elbe nitrogen measurements for this reason.These measurements have shown that regions upstream from […]
2 August 2017 (NOAA) – Scientists have determined this year’s Gulf of Mexico “dead zone,” an area of low oxygen that can kill fish and marine life, is 8,776 square miles, an area about the size of New Jersey. It is the largest measured since dead zone mapping began there in 1985.The measured size is […]
By Damian Carrington 4 June 2017 (The Guardian) – Mining the deep ocean floor for valuable metals is both inevitable and vital, according to the scientists, engineers, and industrialists exploring the world’s newest mining frontier.

By Ker Than14 September 2016 (Stanford University) – An unprecedented pattern of extinction in the oceans today that selectively targets large-bodied animals over smaller creatures is likely driven by human fishing, according to a new Stanford-led study. “We’ve found that extinction threat in the modern oceans is very strongly associated with larger body size,” said […]
By Anika Burgess 6 September 2016 (Atlas Obscura) – With a new report released yesterday into the vast increases in ocean temperatures, human activity on marine life affects all ends of the food chain. Take, for example, the coenobita purpureus, or blueberry hermit crabs, of Okinawa. Like other hermit crabs, they also need shells to […]
By Grant Parpan24 August 2016 (Riverhead News Review) – David Gruner has been visiting the same private beach on the Long Island Sound in Jamesport for more than 50 years.
