Recently in the Ocean Science Category

Using future projections from the latest generation of Earth System Models, a recent study published in Science Advances found that most of the world's ocean is steadily losing its year-to-year memory under global warming.

Every evening, small fish and microscopic animals called zooplankton journey to the ocean surface, where they feast on microscopic plants under the moonlight before returning to the depths at dawn.

Using nearly a decade of satellite data, researchers at Colorado State University have uncovered "milky seas" in a way they've never been seen before - a rare and fascinating oceanic bioluminescent phenomenon detected by a highly sensitive spaceborne low-light sensor.

We're familiar with how climate change is impacting the ocean's biology, from bleaching events that cause coral die-offs to algae blooms that choke coastal marine ecosystems, but it's becoming clear that a warming planet is also impacting the physics of ocean circulation.

Algae might be small, but when they grow out of control, forming harmful algal blooms (HABs), they can cause big problems.

Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important to understanding climate change.

Stranded Whales Detected From Space

A new technique for analysing satellite images may help scientists detect and count stranded whales from space.

Our knowledge of the depth and shape of the Arctic Ocean floor - its bathymetry - is insufficient.

Captured by Sentinel-3A on 23 June 2016, this image shows an algae bloom in the Baltic Sea.

Ice Scours the Caspian Sea

The Operational Land Imager (OLI) on NASA's Landsat 8 satellite acquired this large natural-color image showing a view of the Caspian Sea around the Tyuleniy Archipelago on April 16, 2016.

An international scientific team recently published a new map of the ocean floor based on Earth's gravity field, and it is a particularly useful tool.

A team of NASA and university scientists has developed a new way to use satellite measurements to track changes in Atlantic Ocean currents, which are a driving force in global climate.

The world's oceans have seen significant declines in certain types of microscopic plant-life at the base of the marine food chain, according to a new NASA study.

Phytoplankton communities and sea ice limn the turbulent flow field around Iceland in this Suomi-NPP/VIIRS scene collected on June 14, 2015.

With Earth-observing satellite data, scientists can now monitor the health of coral reefs, even in the most remote regions scattered around the globe where it is otherwise difficult to see changes.

Blooms in the Sea of Marmara

Situated between the Black Sea and the Aegean Sea, the Sea of Marmara is full of a rich soup of nutrients and life and surrounded by a rich history of civilization.

ESA and Airbus Defence and Space today signed a €177 million contract to develop the Jason-CS / Sentinel-6A satellite mission for Europe's Copernicus programme.

Water delivery via asteroids or comets is likely taking place in many other planetary systems, just as it happened on Earth, new research strongly suggests.

Pioneering techniques that use satellites to monitor ocean acidification are set to revolutionise the way that marine biologists and climate scientists study the ocean.

The Operational Land Imager (OLI) on Landsat 8 captured this view of a phytoplankton bloom near Alaska's Pribilof Islands on Sept. 22, 2014.

Hole Punch Clouds over the Bahamas

This true-color image shows hole-punch and canal clouds off the coast of Florida, as observed on December 12, 2014, by the Moderate Resolution Imaging Spectroradiometer on NASA's Terra satellite.

CryoSat Unveils Secrets of the Deep

ESA's ice mission has been used to create a new gravity map, exposing thousands of previously unchartered 'seamounts', ridges and deep ocean structures.

Scientists have created a new map of the world's seafloor, offering a more vivid picture of the structures that make up the deepest, least-explored parts of the ocean.

Climate scientists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles.

Low Clouds Over the English Channel

A thick blanket of low clouds covered the English Channel, Celtic Sea and Irish Sea on March 13, 2014.

Blooming in the South Atlantic

Offshore from Argentina, spring is in bloom. Massive patches of floating phytoplankton colored the ocean in November 2013.

Springtime in the Bay of Biscay

Springtime in the Bay of Biscay, off the coast of France, as in most places, is a season of abundant growth. On April 20, 2013, the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Aqua satellite captured this true-color image of the dynamic growth of a springtime phytoplankton bloom.

Secretary of the Navy Ray Mabus announced today the names of seven ships. Included is an ocean-class auxiliary general oceanographic research (AGOR) ship, the R/V Sally Ride.

Bacteria in Earth's Deepest Trench

An international research team announces the first scientific results from one of the most inaccessible places on Earth: the bottom of the Mariana Trench located nearly 11 kilometers below sea level in the western Pacific, which makes it the deepest site on Earth.

Midway on its 800-kilometer voyage from Auckland to Raoul Island, New Zealand, the HMNZS Canterbury received an intriguing report: a maritime patrol aircraft had spotted a vast area of open ocean covered with floating pumice.

How Much Water Does Earth Have?

As you know, the Earth is a watery place. But just how much water exists on, in, and above our planet? This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth.

Satellites and Ocean Currents

Satellites offer a frequent overview of our entire planet - covered mostly by water - and provide valuable data to monitor and understand global ocean circulation. Understanding water currents at the ocean surface is important for many applications.
