Scientists Predict Third Largest GoM ‘Dead Zone’

Larger-than-average low and no oxygen area in Gulf of Mexico may affect the region’s shrimp fisheries   This summer’s Gulf of Mexico “dead zone” – an area of low to no oxygen that can kill fish and other marine life – is forecasted to be approximately 8,185 square miles, or about the size of New Jersey, U.S. federal scientists predict.   NOAA said this would be the third largest dead zone recorded since monitoring began 32 years ago – the average Gulf dead zone since then has been 5,309 square miles.   The Gulf’s hypoxic or low-oxygen

El Nino Signal is Weakening in the Pacific

The probability of El Nino, a warming of ocean surface temperatures in the eastern and central Pacific, developing this year has been downgraded by U.S. government forecasters as sea surface temperatures and wind speeds in the area remain close to their long-term averages. The Pacific saw a relatively rapid swing in late October from La Nina conditions - characterised as unusually cold temperatures in the equatorial Pacific Ocean - to neutral or even slightly El Nino-leaning conditions by March. Since then, however, the oceanic and atmospheric signals pointing to a possible El Nino have all weakened.

, as inclusive as possible, involving academia, industry and governmental agencies. Tests of JANUS at sea have been conducted in the last years by CMRE on board the NATO Research Vessel Alliance, and using the innovative CMRE Littoral Ocean Observatory Network (LOON), which facilitates experimentation of marine robots’ mission-base teams by creating a monitoring acoustic network with tripods of underwater communications equipment sitting on the seabed but accessible by users across the world via web.

How Deep is the Ocean?

, Mars and Venus than for most of the world’s maritime areas.   In this context, hydrographers make a valuable contribution to the delivery of Sustainable Development Goal 14 on conserving and sustainably using the oceans – whether in support of navigational safety, protection of the marine environment, coastal zone management, defence and security, resource exploration.   Lim highlighted that, since 2002, governments signed up to IMO’s International Convention on the Safety of Life at Sea (SOLAS) are required to provide and maintain hydrographic services and products.

Recovery Comes Slowly for Central Pacific Coral

Nearly one year after prolonged high ocean temperatures caused devastating coral bleaching and loss in parts of Pacific Remote Islands Marine National Monument, NOAA scientists recently went back to check on their condition.   Healthy coral reefs protect shores from storms and offer habitats for fish and other marine life, including ecologically and economically important species. After corals die, reefs quickly degrade and the structures corals build erode. While corals can recover from mild bleaching, severe or long-term bleaching is often lethal.   Jarvis Island, one of the most remote
