High-Resolution Mapping Reveals the Evolution of Underwater Landscapes in the Johnston Atoll

High-Resolution Mapping Reveals the Evolution of Underwater Landscapes in the Johnston Atoll

The mapped region is almost the size of the state of Connecticut and falls within the recently expanded boundaries of a U.S. marine protected area. The area is populated with high-density deep-sea corals and sponges and is of great interest to researchers who view it as a stepping-stone between distinct marine ecosystems in the Northwestern Hawaiian Islands and the Central and South Pacific.

A picture is worth a thousand words

A picture is worth a thousand words

The diversity of shapes and sizes in phytoplankton is overwhelming and beautiful. I was able to see the actual individuals that were in the sea surrounding us all the way across the Pacific. Seeing them first-hand made me realize how interrelated all things are on this planet: they may be invisible, but they are important. We are dependent on them and they on us.

What color is the ocean? The sky?

What color is the ocean? The sky?

What Color is the ocean? The sky? Most of us would reply immediately—blue! But what shade of blue? I am exploring this topic during the research cruise by capturing the blues of the sky and sea through direct observation using my eyes and three instruments—watercolors, photography and a cyanometer.

Far-north mallards thriving on the edge

With dogs’ breath fogging the 30-below zero air at their knees, 71 Iditarod mushers steamed their way down the frozen Chena River in Fairbanks on March 6. Upstream, just a few miles behind them, 500 ducks were surviving in a one-mile stretch of open water.

Phytoplankton sampling strategies

Phytoplankton sampling strategies

Plankton comes from the greek word planktos, meaning wanderer. It does not define a specific organism, but rather a specific life style. Plankton consist of all organisms dispersed in water that are passively driven by water currents or are subject to passive sinking process. Some of those organisms have an ability to produce oxygen and sugars using sunlight and carbon dioxide, just like terrestrial plants do.

Science at sea: Challenges, silver linings and success

Science at sea: Challenges, silver linings and success

Amazingly, the data extracted from the nine sensors in the Wirewalker was complete. This provided new insights about the instrument’s resilience and capabilities. Even with ripped cables and a lost battery pack, it did not miss a beat and came back with an important discovery from Hawaiian waters: the team was excited to confirm a growth in the amount of particles during daytime, which was surprising for two reasons.
