Satellite images of phytoplankton blooms on the surface of the ocean often dazzle with their diverse colors, shades and shapes. But phytoplankton are more than just nature’s watercolors: They play a key role in Earth’s climate by removing heat-trapping carbon dioxide from the atmosphere through photosynthesis.

To answer those questions, this week a large multidisciplinary team of scientists is sailing 200 miles west from Seattle into the northeastern Pacific Ocean with advanced underwater robotics and other instruments on a month-long campaign to investigate the secret lives of these plantlike organisms and the animals that eat them.

Science: Expedition probes ocean’s smallest organisms for climate answers [Report]

NASA and the National Science Foundation are funding the Export Processes in the Ocean from Remote Sensing (EXPORTS) oceanographic campaign. With more than 100 scientists and crew from nearly 30 research institutions, EXPORTS is the first coordinated multidisciplinary science campaign of its kind to study the pathways, fates and carbon cycle impacts of microscopic and other plankton using two research vessels, a range of underwater robotic platforms and satellite imagery. The team will work from the research vessels (R/V) Roger Revelle and Sally Ride, operated by the Scripps Institution of Oceanography, University of California, San Diego.

The word “phytoplankton” comes from the Greek for “plant drifters”; phytoplankton harness the Sun’s energy to transform dissolved inorganic carbon in the ocean into organic carbon’creating carbohydrates and cellular material for nourishment and reproduction’and their movement is largely dictated by the ocean’s physics, including currents. These organisms are microscopic, mostly single-celled, and multiply exponentially, doubling their number on average every day.
Their abundance and high productivity make phytoplankton an ideal food source for small animals called zooplankton, which means “animal drifters” in Greek.

Are you the type of cruiser who just can’t stand a crowd? Our latest Cruise Ship Tour, in the carousel above, offers a deck-by-deck look at what just may be the least-crowded cruise vessel on the world’s oceans, Offshore Outpost Expeditions’ Pacific Provider.’

Specializing in intimate, outdoorsy’getaways in the Sea of Cortez and Alaska, the 163-foot-long “expedition yacht” carries just 12 passengers, despite being a similar size to expedition cruise vessels that hold five times that number.’

UCLA professor plays key role in historic mission to the sun

Marco Velli says space weather can affect everything from astronaut safety to satellites to power plants.
In just a few days, UCLA space physicist Marco Velli will take a deep breath, look to the skies and take his place in history as part of the monumental Parker Solar Probe mission, billed as humanity’s first visit to the sun. The mission launch is scheduled for Aug. 11, although depending on conditions, it may be as late as Aug. 23.
The aim of the expedition, which has been 60 years in the making, is to take the Parker Solar Probe into the the sun’s outer atmosphere, known as the solar corona
