Instrument might assist scientists assess the ocean’s response to local weather change — ScienceDaily

The movement of the ocean is usually considered in horizontal phrases, as an illustration within the highly effective currents that sweep across the planet, or the waves that experience out and in alongside a shoreline. However there may be additionally loads of vertical movement, significantly within the open seas, the place water from the deep can stand up, bringing vitamins to the higher ocean, whereas floor waters sink, sending useless organisms, together with oxygen and carbon, to the deep inside. Oceanographers use devices to characterize the vertical mixing of the…

NASA’s ICESat-2 measures Arctic Ocean’s sea ice thickness, snow cowl — ScienceDaily

Arctic sea ice helps maintain Earth cool, as its vivid floor displays the Solar’s vitality again into house. Every year scientists use a number of satellites and knowledge units to trace how a lot of the Arctic Ocean is roofed in sea ice, however its thickness is more durable to gauge.

Study from previous to guard oceans — ScienceDaily

Historical past holds invaluable classes — and stark warnings — about easy methods to handle fisheries and different ocean sources, a brand new research says. Researchers examined 20 historic examples of fisheries and aquaculture (fish farming), courting from 40 to 800 years in the past. The research, led by the colleges of Exeter, Hull and Boston, discovered constant patterns that resulted in so-called “blue progress” — the event of sustainable ocean economies that benefitted complete communities. It additionally famous frequent “recipes for failure” — and the authors say these provide…
