Rich Waters Of Puget Sound Supplied By Deep, Turbulent Canyon
2014-04-15 10:32:02

By Hannah Hickey, University of Washington The headwaters for Puget Sound's famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest's inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales. University of Washington oceanographers made the first detailed measurements at the headwater's source, a submarine canyon...

Submarine Canyons Important Source Of Marine Invertebrate Diversity, Abundance

University of Hawaiʻi at Mānoa Submarine canyons play an important role in maintaining high levels of biodiversity of small invertebrates in the seafloor sediments of the main and northwestern Hawaiian Islands, according to research from the University of Hawai‘i at Mānoa. What’s more, scientists have used this data to draw new connections between the levels of faunal diversity and the heterogeneity of submarine canyon landscapes at various spatial scales. “Submarine canyons...

Underwater canyons have long been considered important habitats for marine life, but until recently, only canyons on continental margins had been intensively studied. Researchers from Hawaii Pacific University (HPU) and the University of Hawaii at Manoa (UHM) have now conducted the first extensive study of canyons in the oceanic Hawaiian Archipelago and found that these submarine canyons support especially abundant and unique communities of megafauna (large animals such as fish, shrimp,...

Surplus food can be a double-edged sword for bottom-feeders in the ocean deep, according to a new study in the April issue of Ecology. While extra nutrients give a boost to large animals on the deep sea floor, the feeding frenzy that results wreaks havoc on smaller animals in the seafloor sediment, researchers say. Descend thousands of feet under the ocean to the deep sea floor, and you'll find a blue-black world of cold and darkness, blanketed in muddy ooze. In this world without sunlight,...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
