Galápagos Islands unique ecosystem involving trade winds and EUC
Trade winds push surface water west, while an eastward undercurrent hits the Galápagos, lifting deep, nutrient-rich water that fuels its unique ecosystem.

Arctic map showing vessel track and coastal transport sources for increased Radium levels measured offshore indicating changing climate conditions.
Read MoreHow a DMON buoy operates to detect and transmit right whale location info
DMON buoys detect whale calls and transmit information about them from the cable to the buoy, which relays the information to a satellite and ultimately to scientists in near-real time.
Read MoreHow a hydrothermal vent system works
Hydrothermal vents form in places where there is volcanic activity, such as along the Mid-Ocean Ridge.
Read MoreHow a Thermal Glider operates autonomously in the ocean
This robotic vehicle can propel itself for several months across thousands of miles, using only heat energy from the ocean.
Read MoreHow antibacterial resistant bacteria spreads resistance
Antibiotics in human waste can end up in the ocean, where they increase the risk that marine bacteria will develop resistance to antibiotics.
Read MoreHow biological compounds from phytoplankton blooms enter the atmosphere
Biological compounds from phytoplankton blooms could end up trapped in centuries-old ice cores that scientists can use to measure ocean productivity over time.
Read MoreHow blue holes are formed
These sinkholes formed on dry land during the last ice age, when much of the Earth’s water was frozen in ice sheets and sea levels were almost 400 feet lower than today.
Read MoreHow Cyanobacteria Crocosphaera watsonii recycles iron
Iron is scarce in the ocean, but a key marine bacterium may have evolved a remarkable biochemical way to recycle it and reduce its iron requirements by half.
Read MoreHow the Fraser River picks up chemical signatures along its journey
Samples from the Fraser River help scientists track a geochemical journey that starts in the atmosphere, moves through rocks and plants, and sinks to the seafloor.
Read MoreHow the Pacific influences rainfall in Asia
Maps comparing the connection between the Pacific and Indian Ocean regions in the equatorial region, during El Nino/La Nina conditions.
Read MoreHow Trichodesmium are essential cogs in the ecological machinery of the ocean
Trichodesmium are essential cogs in the ecological machinery that cycles chemicals through the oceanschemicals that sustain life and influence global climate.
Read MoreHydrophone on mooring listening to Bowhead whale
Scientists track bowhead whales in icy regions by recording their changing songs, studying how whales adopt new tunes to communicate and attract mates.
Read MoreIcy wind blows from the Antarctic Continent
New research suggests that fresh melt water from icebergs creates a fresher version of bottom water, with potentially significant consequences for the ocean and climate.
Read MoreAir-sea exchange mechanisms
Climate change shifts Earth’s water cycle, increasing rain in wet areas and drought in dry ones. Scientists study how water moves between ocean and air.

Read MoreDeep Water Horizon oil spill dispersant theory scenarios
Oil droplets from deep wells can be broken into small, neutrally buoyant droplets by dispersants, helping microbes degrade them before they reach the surface.

Deepwater Horizon Gulf oil spill timeline of events.
Read MoreEstrogens comes in several "flavors"
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.
Read MoreDetail of lipids in cell membranes
The cell membranes of single-celled marine life are mostly made of fatty compounds called lipids.
Read MoreTaking a deeper look at Deep-Sea
Deep-See carries camera systems, sonars, and sensors for measuring currents and seawater properties in the ocean twilight zone, as well as a sampling device.
Read MoreDevelopment of a rip current along a coastal beach
Waves, currents, and seafloor shape interact in coastal surf zones, moving sand and water up, down, and along the shore, constantly reshaping the coastline.
Read MoreDiagram demonstrating how a Slocum glider operates in the water column
An ocean glider moves up and down in the water column collecting data, surfacing to get a GPS reading on its position and to exchange data with scientists back on shore.
