Description of estrogen types and potency production
Estrogens are hormones that are essential for growth and development, but even minuscule amounts of excess estrogen can have detrimental health impacts on living things. The core of estrogens is…
Read MoreDetail of lipids in cell membranes
The cell membranes of single-celled marine life are mostly made of fatty compounds called lipids. They have a distinctive structure with hydrophilic (water-loving) “heads” and hydrophobic (water-avoiding) “tails” and are…
Read MoreDetails about and sample imaging from Deep-See
Weighing about 2,500 pounds and 16 feet in length, the Deep-See carries camera systems, sonars, and sensors for measuring currents and seawater properties in the ocean twilight zone, as well…
Read MoreDevelopment of a rip current along a coastal beach
Many forces intersect and interact in the surf and swash zones of the coastal ocean, pushing sand and water up, down, and along the coast. Variations in the height and…
Read MoreDiagram demonstrating how a Slocum glider operates in the water column
An ocean glider has no propeller and moves up and down in the water by changing its buoyancy. A glider cannot receive or transmit data under water. It has to…
Read MoreDiagram showing the flow of the North Atlantic and Norwegian Atlantic Currents
The North Atlantic and Norwegian Atlantic Currents carry warm, salty, tropical surface waters northward, where they surrender heat to the atmosphere, tempering winters in Europe. The waters become colder and…
Read MoreDiatoms and Coccoliths carbon-dioxide carbon removal from atmosphere
Conditions that influence removal of carbon-dioxide carbon from atmosphere to deep ocean are illustrated here and discussed in the article. (Illustration by Jack Cook, © Woods Hole Oceanographic Institution)
Read MoreDrawing of Timoides agassizii by Henry Bigelow
Pioneering marine biologist Henry Bryant Bigelow served as the founding director of Woods Hole Oceanographic Institution from 1930 to 1939. Almost three decades earlier, when Bigelow was an undergraduate at…
Read MoreDrifter plot and radioactive substance levels plot relating to Fukushima
BOTTOM: An international scientific team led by WHOI marine chemist Ken Buesseler completed a research cruise in June 2011 to assess the levels and dispersion of radioactive substances from the…

Read MoreEruptions along the North American Plate and Yellowstone hotspot
The North American Plate has slowly moved westward over an active magma chamber, leaving a trail of past eruptions on the landscape. The hot spot now lies beneath Yellowstone Park.…
Read MoreFirst drawn map of the Titanic wreck site
Following the 1985 French-American expedition that discovered the wreck of Titanic, WHOI researchers William Lange, Elazar Uchupi, and Bob Ballard examined all the still and video images captured by deep-sea…
Read MoreBiomass of mesopelagic organisms in Ocean Twilight Zone (OTZ)
The ocean twilight zone 200 to 1,000 meters (660 to 3,300 feet) beneath the surface teems with life. Spanning the entire world, its waters are vast, dimly lit, and under…
Read MoreCarbon drawn into the ocean by plankton sinks and dissipates with depth
THE BOTTOM LINE—Only a small fraction of the carbon drawn into the ocean by plankton blooms makes it into the depths where it no longer can be exchanged with the…
Read MoreCarbon emissions projection featuring possible reduction methods called “wedges”
CLOSING THE GAP—With improvements in technology, but no changes in climate or carbon policies (the so-called “business-as-usual” scenario), carbon emission levels are projected to continue to rise (orange line) far…

Read MoreChemical process by which phytoplankton and harmful algal blooms grown
Phytoplankton, including harmful algae, need the right combination of ingredients to grow. They need sunlight, which is bright near the surface but gets dimmer with depth. They need nutrients, such…

Read MoreCO Solubility Pump
Solubility Pump: Many different gases dissolve in seawater including oxygen, nitrogen and carbon dioxide. Solubility of CO2 is strongly dependent on temperature, among other factors. The colder the water, the…

Read MoreComparison of oil dispersant effectiveness in different weather
A recent study by WHOI scientists Collin Ward and Chris Reddy showed that sunlight plays a critical and previously overlooked role in oil spills. Light energy rapidly alters the chemistry…
