Temperature & Chemistry

How and why do ocean temperatures fluctuate throughout the ocean? Not only are there massive temperature changes in the ocean (called a thermocline), but also swift changes in salt, oxygen and other chemicals that can tell scientists a lot.

Taking the Ocean’s Temperature

A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit...

The Gulf Oil Spill: Effects on Marine Life

The Deepwater Horizon disaster has imperiled the ecosystem along the U.S. Gulf Coast. Most oil spills have occurred at the ocean surface. This one, originating at the ocean floor and rising up through the...

Taking the Ocean’s Temperature

A fleet of underwater floats called Argo is deployed at more than 3,000 spots around the world. The floats transmit information about water temperature, salinity, and pressure which scientists use to understand trends in...

Lecture: One Year After the Gulf Oil Spill

On April 20, 2010, the Deepwater Horizon oil rig exploded, opening up a well that pumped nearly 5 million barrels of oil into the ocean. It was the largest spill in U.S. history. In...

Scientists Work to Predict and Prevent Algae Blooms

Harmful algal blooms are dangerous, producing toxins that can kill marine organisms, taint shellfish, cause skin irritations, and even foul the air Credit: Flickr User AJC1 Algae, like all organisms, normally grow in balance...

Line W: A 10-Year Portrait of Our Planet

The Woods Hole Oceanographic Institution's "Line W" program is conducting research to better understand how the oceans and the atmosphere work together to cause, and are affected by, climate variability on the earth. Since...

Exploring Ocean Life with an Underwater Vehicle

Studies along the Northwest Atlantic Ocean shelf break- the transition from continental shelf to slope- by researchers from Woods Hole Oceanographic Institution and Rutgers University are revealing connections between physical processes in the ocean...

Searching for the Ocean Acidification Signal

Over that past century, the pH of the ocean has decreased from 8.2 to 8.1. This doesn’t seem like a lot, but it represents a faster rate than at any time in the last...

Ocean Acidification

Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because...

Ocean Acidification with Dr. Francisco Chavez

Dr. Francisco Chavez of the Monterey Bay Aquarium Research Institute estimates that a million tons of CO 2 enter the ocean hourly. His studies in Peru explore the phenomenon of ocean acidification, which occurs...

How a Microscopic Team Alters the Course of Carbon in the Atlantic Ocean

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic Ocean. This...

Climate Change Effects on Glaciers and Ice Sheets

How will changes in temperature affect glaciers and ice sheets? Dr. Sarah Das from the Woods Hole Oceanographic Institution explores this phenomenon first hand in Greenland, where she studies how the melted ice travels...
