Scientists, students to conduct first live, interactive public broadcasts from arctic ocean

"A team of natural and social scientists, supported by 25 post-secondary students from the U.S. and Canada, will study vital signs of a rapidly changing Arctic Ocean this summer, and offer the public a chance to share the experience in real time.

The innovative, 18-day Northwest Passage Project research expedition will depart on July 18 from the U.S. Air Base in Thule, Greenland, aboard the Swedish Icebreaker Oden, returning to Thule August 4 after a 2,000 nautical mile voyage through the Northwest Passage [...]"

Investigator Voyage to Address Puzzle of Southern Ocean Current

"An IMAS-led voyage on the Marine National Facility research vessel Investigator today sailed from Hobart with scientists aiming to solve a Southern Ocean puzzle with important ramifications for the global climate.

The researchers will survey a ‘standing meander’ south of Tasmania that they hope will help them to understand why the east-flowing Antarctic Circumpolar Current (ACC) has remained constant despite westerly winds strengthening by 20% over the last two decades. [...]"

Fleet of sailboat drones could monitor climate change’s effect on oceans

"Two 7-meter-long sailboats are set to return next month to California, after nearly 8 months tacking across the Pacific Ocean. Puttering along at half-speed, they will be heavy with barnacles and other growth. No captains will be at their helms.

That is not because of a mutiny. These sailboats, outfitted with sensors to probe the ocean, are semiautonomous drones, developed by Saildrone, a marine tech startup based in Alameda, California, in close collaboration with the National Oceanic and Atmospheric Administration (NOAA) in Washington, D.C. The voyage is the longest test for the drones and also the first science test in the Pacific—an important step in showing that they could replace an aging and expensive array of buoys that are the main way scientists sniff out signs of climate-disrupting El Niño events. [...]"

M/V Columbia starts its study of ocean acidification

"An Alaska state ferry recently started work doubling as an ocean research platform.

The M/V Columbia, which conducts weekly runs between Bellingham, Washington and Alaska, has been installed with a seawater monitoring system to study ocean acidification, a byproduct of human-caused climate change which could affect sea life in Alaska and around the world. [...]"

Project: Kelp Forest Array

The Kelp Forest Array (KFA) is a state-of-the-art cabled platform for observational and experimental science aimed at monitoring and understanding local impacts of global climate change. Increasing climate change and ocean acidification pressures require the establishment of long-term, baseline monitoring methods to document how a currently healthy system changes and to understand effects of climate change in relation to this natural variability. Current monitoring practices limit resolution and longevity of baseline data sets.

Synthesis and Integrated Modeling of Long-Term Data Sets to Support Fisheries and Hypoxia Management in the Northern Gulf of Mexico

"We are integrating existing data sets collected in the Northern Gulf of Mexico to study hypoxia impacts on coastal ecosystems and associated fisheries. We are using probabilistic, data-centric modeling to assess the spatiotemporal dynamics of hypoxia and to understand and forecast fisheries and ecosystem impacts. Our research focuses on data-driven inferences driving hypoxia and fisheries dynamics, rigorous uncertainty quantification, and prudent forecasting methodologies for all coastal areas."

Using Linked Models to Predict Impacts of Hypoxia on Gulf Coast Fisheries Under Scenarios of Watershed and River Management

"We are linking a suite of well-established models to quantify fish and shrimp population responses to combinations of nutrient loadings and planned river diversions. Our scenario analyses include different land-use and agricultural practices in the watershed and alternative river diversions. The linked model system informs and supports management decisions by estimating how reduced nutrients and diversion operations affect hypoxia and key living resources."

Four-month Cruise with German RV METEOR off Peru

Collaborative Research Centre 754 investigates oxygen minimum zone in the Southeast Pacific

Last week, the first of four consecutive expeditions with the German research vessel METEOR started in Valparaiso (Chile) to investigate the oxygen minimum zone off the coast of Peru. For four months scientists from Kiel's Collaborative Research Center 754 “Climate - Biogeochemical Interactions in the Tropical Ocean” will examine the consequences of global change for the oxygen distribution in the tropical East Pacific, as well as the regional biological, chemical and environmental impacts.

"The deep sea is the largest environment on the planet. Most of the deep sea consists of the water column above the seafloor, the pelagic zone. In many parts of the pelagic ocean, no scientific sample or observation has ever been collected. Consequently, knowledge on deep-sea pelagic biodiversity and on the biology and ecology of organisms in this realm remain largely unknown.
During MSM61 we perform deployments with the pelagic in situ observation system or PELAGIOS. This ocean instrument collects high definition video during horizontal transects while being towed on a CTD cable at various depths of interest.[...]"
