NASA to study tiny sea creatures to understand Earth's climate

IANS  |  Washington 

In a first, a team of scientists from NASA are on a research mission to study -- the tiny sea creatures -- and their impact on the atmosphere and climate on Earth.

The Aerosols and Marine Ecosystems Study (NAAMES), which is in its fourth and final deployment stage, is set to study to four distinct phases of the world's largest bloom in the

Previous three deployments have confirmed a distinct shift in the annual cycle of the bloom as well as a lack of larger-sized during the peak of the bloom.

"Most scientists studying the to sea during its climax in late spring and early summer. We did that, but we also went out during the other seasons to fully capture the minimum and transitions of the bloom," Rich Moore, at NAAMES, said in a statement.

"This thoroughness pays off as our ship-based scientists use these data to fully describe the entirety of the bust/boom cycle.

"No one has done this before, and we're excited about the science findings that are beginning to trickle out now," Moore said

The study is set to research the "ascending transition" of the bloom, which occurs after the minimum in February.

In the March-April phase, the are growing steadily, with their abundance in the water continuing to increase or accumulate toward the maximum of the bloom between May and July.

The NAAMES campaign also provides a unique opportunity for researchers aboard Atlantis to do experiments that study growth and decay of the population.

"For scientists watching the rates of growth, this is the exciting time, because the accumulation rate is expected to be going through the roof and stay high for the next few months," Moore said.

Rates of accumulation are critical for understanding the ocean conditions that lead to growth and its timing, a key to unlocking the environmental drivers and controls of biological dynamics, the report said.

For the study, the team is combining global data from NASA satellites with the ship, aircraft, and autonomous assets such as floats, along with laboratory research and balloon data.

Scientists are also conducting meteorological balloon launches from the ship to understand the link between the ocean, atmospheric particles and clouds.
