Original sketch of Titanic wreck site debris field
Hand drawn map of the wreck and surrounding debris field was created by the 1986 exploration team. Details were added to the map as the daily dives were completed.
Read MoreOTZ Mixing Pump and Migration Pump
Each night, millions of ocean animals migrate upward to feed, then descend at dawn, actively transporting carbon from surface waters to the deep in Earth’s largest animal migration.
Read MorePhotosynthesis process featuring its light and dark stages
To cope with fluctuating light levels, many phytoplankton have accessory pigments that can change structure and to send more or less energy to choloroplasts.
Read MorePlates Collide
When continents collide, crust buckles and forms mountain ranges like the Himalayas, which began rising 45 million years ago and still grow as plates push together today.
Read MorePlates Separate
Mid-ocean ridges and rift valleys form where tectonic plates spread apart, creating new ocean crust as molten rock rises, causing earthquakes and volcanic eruptions along the way.
Read MorePlates Slide
Transform faults form where plates slide past each other, causing powerful quakes. The San Andreas Fault between Pacific and North American Plates fuels major California earthquakes.
Read MorePlates Subduct
When ocean plates collide, one subducts beneath the other, forming trenches and causing molten rock to rise, creating volcanic mountains or island arcs like Japan or the Andes.
Read MoreProcess showing how methane is derived from photosynthetic bacteria
Scientists discovered that photosynthetic bacteria in surface waters produce sugar chains broken down by other bacteria, releasing methane—a new microbial source of this greenhouse gas.
Read MoreA Krill’s Life Cycle
Krill hatch deep and race upward to survive—only those reaching the surface before winter can feed, grow, and live through their first icy Antarctic season.
Read MoreRainfall prediction illustration
Spring winds boost Atlantic salinity, fueling summer rains in Africa and the U.S. via soil moisture buildup, convection, and increased moisture transport.
Read MoreRecent Past and Near-Future Sea Level Rise Rates
Dispersants break oil into tiny droplets using detergents and solvents, but sunlight quickly weakens their effectiveness on oil floating at the sea surface.
Read MoreA microbial garden beneath the seafloor
Chemical reactions below the seafloor create energy-rich fluids that sustain a vast, diverse microbial biosphere adapted to specific underground niches.
Read MoreA smorgasbord of chemical reactions
Deep-sea microbes thrive near hydrothermal vents by using diverse chemical reactions—both with and without oxygen—to extract energy and grow underground.
Read MoreRight whale detection mooring operation
To quiet noisy recordings in rough seas, WHOI engineers created a two-tiered mooring. A bungee-like top line absorbs motion, keeping the hydrophone stable below.
Read MoreRopeless fishing technology to release a trap line entangling a right whale
WHOI engineers created a ropeless fishing system that releases lines using acoustic signals—now moving from successful land tests to at-sea trials and refinements.

Map from 2014 showing sea surface temperatures with a glider track highlighting a warm-water intrusion called Pinocchio’s Nose.
Read MoreScale depicting the concentration of pH and examples of solutions
Seawater is becoming more acidic as CO? levels rise. Even small drops in pH can harm marine life that builds shells or skeletons from calcium carbonate.
Read MoreScallop Life Cycle being affected by ocean acidification
Climate change and ocean acidification could wipe out over half of Atlantic sea scallops in 3080 years—unless strong management and CO? cuts slow the trend.
Read MoreGroundwater cycle
Groundwater flows into the ocean through coastal sediments, carrying chemicals that can impact ocean chemistry—an overlooked part of Earth’s water cycle.

Read MoreMicrobial "Trojan horses" stages
Some bacteria ingested by protists escape digestion, survive, and even reproduce—eventually returning to the environment, potentially still infectious.
Read MoreMicrobial Life Tree
Genetic analyses trace deep-sea microbes’ diverse metabolic paths across bacteria, archaea, and eukaryotes, unveiling life’s complex tree.
Read MoreMicroplastics breaking down in different areas of the environment
Scientists study how larger plastics break down into microplastics, exploring land and ocean processes like sunlight, temperature, and abrasion that cause plastic fragmentation.
Read MoreMicroplastics in the Food Chain illustration
Plastics that get into the ocean often degrade into microplastics that are ingested by fish and shellfish and can go up the food chain to be ingested by humans.
