Know Your Ocean <http://www.whoi.edu>

"Know your Ocean" Science Chats are an annual, summertime series of 
publicly accessible talks by scientists and engineers at the Woods Hole 
Oceanographic Institution. All talks take place on Tuesdays at 3:00 p.m. 
in WHOI's Ocean Science Discovery Center Auditorium, 15 School Street 
<https://www.google.com/maps/place/15+School+St/@41.52452,-70.668391,17z/data=%213m1%214b1%214m2%213m1%211s0x89e4d87de31ceff5:0xf7258795d0a0ea57>, 
Woods Hole.

Is Alien Life Closer than We Think?

*Chris German, senior scientist, WHOI Geology & Geophysics Department*
Not all life on Earth depends on sunlight. One of the biggest 
discoveries in ocean science at the end of the last century is that life 
can also exist in the absence of photosynthesis. This life is sustained 
by energy released at the ocean floor when seawater and rocks interact: 
a process known as chemosynthesis. Since 2000, it has become apparent 
that saltwater oceans also exist in abundance (much more than on Earth) 
throughout the solar system. Now, WHOI researchers are preparing to 
collaborate with NASA scientists and engineers to search for life beyond 
Earth. Their targets are not the oceans of exoplanets yet to be found 
orbiting distant stars, but right here in our own solar system—within 
the reach of robots that can be launched in the next decade.

Fueling the Future

*Scott Lindell, research specialist, WHOI Applied Ocean Physics and 
Engineering*
In the future, our homes and vehicles could be powered by fuel made from 
seaweed grown at large-scale offshore farms. Currently in the U.S., 
macroaglage (seaweed) is primarily used in food and food processing for 
humans and animals, and a majority are from imported farmed product or 
wild harvests. Seaweed farming avoids the increasing competition for 
fertile land, energy-intensive fertilizers, and freshwater resources 
associated with traditional agriculture. Learn how WHOI scientists and 
engineers in the MARINER (Macroalgae Research Inspiring Novel Energy 
Resources) projects are addressing the global issues of food and energy 
demand with innovative solutions.

Why are Cape Cod Estuaries Impaired and What Can Be Done About It?

*Matt Charette, senior scientist and director of Woods Hole Sea Grant*
Learn how researchers at Woods Hole Oceanographic Institution are 
studying how the unique geology of Cape Cod and a housing boom led to 
nutrient over-enrichment of our estuaries and the unique alternative 
solutions that towns in the region are considering to address the problem.

Fifty Years at WHOI: Studying Extremes of Life in the Cold and Hot Deep Sea

*Carl Wirsen, oceanographer emeritus, WHOI Biology Department*
The world’s oceans have an average depth of 3,500 meters, and the deep 
sea is the largest biosphere on Earth both by area and by volume. Learn 
how research on how microbes have adapted to living under the cold 
temperatures, high pressures, and low nutrients of the deep sea was 
sparked by the accidental sinking and subsequent recovery of the 
submersible Alvin in 1968 and 1969. On the flip side, when deep-sea 
hydrothermal vents were discovered some 40 years ago, researchers 
branched into studying these rich oases of life. Vent sites are home to 
many previously unknown microbes and animals. They rely on energy from 
the inner earth to supply the chemicals for growth, rather than 
photosynthetically supplied food that sparsely rains down to nourish the 
majority of the deep sea. In these extreme vent environments, life at 
the highest temperature known to exist on our planet has been found—121° 
C (or 250°F). Years of research using both ships and submersibles such 
as Alvin have helped us gain insight into their growth and survival and 
also taught us that the deep sea is not a wise choice as a site for 
waste disposal or seafloor mining.
