PACE Science and Applications Team Research Opportunity

[15-Mar-19] The purpose of the NASA NSPIRES solicitation (NNH19ZDA001N-PACESAT) is to formulate a Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) Science and Applications Team (SAT) for a three-year period (FY20-22). The team will encompass basic and applied research and applications, using data from precursors to OCI, HARP-2, and SPEXone. The PACE mission is to include an ocean color sensor and one or more aerosol/cloud polarimeters, in order to produce data to maintain a time series of critical climate and Earth system variables.

ROSES-18 Amendment 67: New Opportunity in A.48 PACE System Vicarious Calibration

[25-Feb-19] ROSES-18 Amendment 67 presents a new opportunity in program element A.48, Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) Mission System Vicarious Calibration. MORE

Spaceflight SSO-A: SmallSat Express Launches

[03-Dec-18] On Monday, December 3rd at 10:34 a.m. EST, SpaceX successfully launched Spaceflight SSO-A: SmallSat Express to a low Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. A series of six deployments occurred approximately 13 to 43 minutes after liftoff, after which Spaceflight began to command its own deployment sequences. MORE

Invasive Algal Blooms Discussed on SciTech Now

[24-Sep-18] Arabian Sea algal blooms are taking over the base of the food chain which could prove catastrophic for 120 million people living on the sea’s edge. Joaquim Goes, Research Professor at Columbia University's Lamont-Doherty Earth Observatory in New York City joins Hari Sreenivasan to discuss this growing problem on Public Broadcasting Systems' "SciTech Now." MORE

Expedition Probes Ocean's Smallest Organisms for Climate Answers

[08-Aug-18] 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. MORE

NASA's Ocean-Watching Mission Gets Jazzy, Colorful New Videos

[26-Jul-18] Four new videos showcase NASA's ocean-watching PACE mission with moving mosaics, stop-motion animation and jazz. The animations (which can also be viewed in the PACE video gallery) take on topics of biodiversity, harmful algal blooms, aerosols, and fisheries. MORE

NASA, NSF Plunge Into Ocean 'Twilight Zone' to Explore Ecosystem Carbon Flow

[18-Jun-18] A large multidisciplinary team of scientists, equipped with advanced underwater robotics and an array of analytical instrumentation, will set sail for the northeastern Pacific Ocean this August. The team's mission for NASA and the National Science Foundation (NSF) is to study the life and death of the small organisms that play a critical role in removing carbon dioxide from the atmosphere and in the ocean's carbon cycle.

Improved Ocean Color Data Software is Released

[09-May-18] SeaDAS is a comprehensive software package for the processing, display, analysis, and quality control of ocean color data. Originally developed to support the SeaWiFS mission, it now supports most U.S. and international ocean color missions. A new release, Version 7.5, includes over 1700 code updates that have resulted in enhanced statistical tools, help features, and other improvements. SeaDAS is available from the Ocean Biology Distributed Active Archive Center (OB.DAAC) at Goddard Space Flight Center. MORE

A Novel Approach to a Satellite Mission's Science Team

[12-Feb-18] The NASA Plankton, Aerosol, Cloud, Ocean Ecosystem (PACE) mission, with a target launch within the next 5 years, aims to make measurements that will advance ocean and atmospheric science and facilitate interdisciplinary studies involving the interaction of the atmosphere with ocean biological systems. Unique to this Earth science satellite project was the formation of a science team charged with a dual role: performing principal investigator (PI)-led peer-reviewed science relevant to specific aspects of PACE, as well as supporting the mission's overall formulation as a unified team.

NASA Taking Stock of Phytoplankton Populations in the Pacific

[03-Feb-17] The microscopic size of phytoplankton, the plant-like organisms that live in the sunlit upper ocean, belies their importance in the global environment. They provide the food source for the zooplankton that ultimately feed larger animals ranging from small fish to whales. And like plants on land, phytoplankton use carbon dioxide from the atmosphere to grow and thrive through photosynthesis, which ultimately releases oxygen into the ocean and atmosphere. MORE
