Even when a whale dies an unnatural death, its body joins the ocean’s vast circle of life. And very often, that circle is very messy, and it involves sharks. WHOI’s Dr. Michael Moore speaks with The Atlantic about a feeding frenzy in the Atlantic Ocean.
Submarines can descend thousands of feet below the surface of the ocean, but to do so, they have to deal with an enormous amount of pressure. NPR caught up with WHOI’s Bruce Strickrott, Group Manager and Chief Pilot of the Deep Submergence Vehicle Alvin, who explains some of the fundamental engineering principles that allow submarines to dive so deep without imploding under the pressure, and shares updates on Alvin’s overhaul and future dives.
Human Occupied Vehicle (HOV) Alvin is part of the National Deep Submergence Facility (NDSF). Alvin is one of the most recognized deep submergence vessels in the world and the only one in the U.S. capable of carrying humans into extreme ocean depths. The sub has completed 5,065 successful dives, more than all other submersible programs worldwide combined. When Alvin relaunches next fall, the iconic sub will have the ability to dive to 6500 meters (21,325 feet)—almost 4 miles deep and 2,000 meters deeper than Alvin’s current maximum depth of 4500 meters (14,800 feet). The upgrade will also give the sub access to 99% of the ocean floor.
Scientists have discovered bacteria from the deep sea with components that are unrecognizable by the human immune system and may hold important properties in the development of cancer treatments and vaccines, according to a collaborative study published in Science Immunology.
According to WHOI, the Falmouth planning board approved the name change of a street that winds through its campus…from Maury Lane to Marie Tharp Lane.
Some invasive species targeted for total eradication bounce back with a vengeance.
It’s been encouraging to watch the marine life rebound without the pressure of local fisheries.
Following the screening, Starrett’s daughter, Dr. Amy Bower, an oceanographer at the Woods Hole Oceanographic Institution, will be joined in conversation by Cape Ann environmental 3-D artist Sinikka Nogelo and the nationally-known public artist Mags Harries.
Running out of space to build more tanks, the government wants to gradually release the water into the sea – after it has been decontaminated and diluted – over the next three decades or more.
As a U.S. Navy officer and NASA astronaut, Wendy B. Lawrence spent over 20 years of her life serving her country both on planet Earth and in outer space.
“North Atlantic right whales face a serious risk of extinction, but there is hope if we can work together on solutions. Trauma reduction measures and applying new tools to assess their health are critically important to enhance the welfare of individual whales. If we can reduce the number of deaths, and successfully improve their health (and increase their) reproduction, the current decline in population can be reversed,” says lead study author Michael Moore, a whale trauma specialist at Woods Hole Oceanographic Institution.
The Indian National Centre for Ocean Information Services (INCOIS) is planning to take the help of the National Remote Sensing Centre (NRSC) for airline mapping of Andaman and Nicobar Islands and Lakshwadeep to get a better picture of the ocean floor, also called ‘bathymetric’ study.
The U.S. Coast Guard’s sole heavy icebreaker, Polar Star, recently broke the nation’s 40-year winter absence from icy waters above the Arctic Circle while on a 12-week deployment to the Bering Strait region.
Since Charles Darwin’s day, the abundance of life on coral reefs has been puzzling, given that most oceanic surface waters in the tropics are low in nutrients and unproductive.
The scientists believe that this offshore energy may be entering the food web through lower-level plankton feeding fish that the groupers are then feeding on. This is likely to be supported by inputs of nutrient-rich deep water, which are little understood.
Soule talks to Physics World’s James Dacey about doing science in the Alvin submersible vehicle, which is currently be refurbished to allow it to reach the astonishing depth of 6.5 km.
