San Juan Seamount: An Ancient Archipelago

By Samuel Georgian, Marine Biogeographer at Marine Conservation Institute San Juan Seamount Seamounts are massive underwater mountains – usually extinct volcanoes – that tower thousands of feet above the seafloor. Some seamounts however, including the San Juan Seamount off the coast of southern California, were once ancient islands. San Juan started to form approximately 20 Read more about San Juan Seamount: An Ancient Archipelago[…]

Cortes and Tanner Banks: Recreation and Biodiversity Hotspots

By Samuel Georgian, Marine Biogeographer at Marine Conservation Institute Cortes and Tanner Banks Cortes and Tanner Banks are twin seamounts located approximately 80 miles off the coast of California, and just five miles from each other. As recently as 10,000 years ago, the banks would have been classified as islands instead of seamounts, as rocky Read more about Cortes and Tanner Banks: Recreation and Biodiversity Hotspots[…]

Deep But Not Deserted – Exploring Deep-Sea Ecosystems Off the California Coast

By Dr. Samuel Georgian, Marine Biogeographer at Marine Conservation Institute In July 2018, Marine Conservation Institute staff scientist Samuel Georgian stepped on board the NOAA research vessel Bell M. Shimada, beginning a two-week expedition to explore deep-water coral and sponge habitats off the coast of northern California. In conjunction with NOAA’s Cordell Bank National Marine Sanctuary Read more about Deep But Not Deserted – Exploring Deep-Sea Ecosystems Off the California Coast[…]

Expedition Planning 101 – How Models Can Help Guide Deep-Sea Exploration

By Dr. Sam Georgian, Marine Biogeographer at Marine Conservation Institute In May 2018, a joint Marine Conservation Institute and Marine Applied Research and Exploration (MARE) expedition will probe the deep seafloor within the Channel Islands National Marine Sanctuary. The sanctuary is home to an astonishing diversity of cold-water corals and sponges that build crucial habitat Read more about Expedition Planning 101 – How Models Can Help Guide Deep-Sea Exploration[…]

5 Reasons Seamounts Matter

By Matt Coomer, Communications Coordinator at Marine Conservation Institute Seamounts are underwater mountains that rise from the seabed. Because most of the world’s seafloor is a muddy plain, seamounts are special deep-sea features that support unique creatures. Seamounts can arise along mid-ocean ridges, as isolated landmarks, or as volcanoes in chains and clusters. Off California, Read more about 5 Reasons Seamounts Matter[…]

Needle in a haystack: identifying vulnerable marine ecosystems in the deep sea

By Dr. Samuel Georgian, Marine Biogeographer at Marine Conservation Institute  Seamounts are underwater mountains rising thousands of feet from the bottom of the ocean. Due to their size and shape, seamounts exert a strong influence on local currents that results in nutrient enrichment and increased food supply. As a result, these massive features are often Read more about Needle in a haystack: identifying vulnerable marine ecosystems in the deep sea[…]
