Scientists are extremely interested in the Arctic seafloor because it has undergone very dramatic changes due to climate change. In collaboration with Canadian colleagues, MBARI researchers led by Charles Paull embarked on a Canadian icebreaker, the CCGS Sir Wilfred Laurier, to explore the unique undersea geology of the area.
Jan 30, 2013 – Hidden beneath ocean waves and masked by sand and mud on the seafloor, underwater faults are notoriously difficult to see and even more difficult to study. As a result, geologists struggle to evaluate the risks associated with these faults and often can’t include them in seismic hazard assessments.
May 11, 2012 – “As the remotely operated vehicle (ROV) descended into the blue depths above the Alarcón Rise, the control room was abuzz with anticipation,” wrote MBARI geologist Julie Martin in her April 22nd cruise log. “Today we [are] planning to dive on one of the strangest environments in the deep sea: a hydrothermal vent field.”
MBARI’s seafloor mapping robot has had a busy year. It documented a huge lava flow from a three-month-old volcanic eruption off the Oregon coast; it charted mysterious three-kilometer-wide scour marks on the seafloor off Northern California; and it unearthed data that challenge existing theories about one of the largest offshore faults in Central California.
