STAR Seminars

Welcome to the STAR science seminar listings page. The STAR seminar series listings include STAR seminars, NOCCG seminars starting in 2019, and CoastWatch seminars, newly added for 2022.

NOAA's Ocean Color Coordinating Group (NOCCG) is a NOAA organization founded in 2011 by Dr. Paul DiGiacomo, Chief of SOCD at NOAA/NESDIS/STAR and was formally recognized by NESDIS in response to the National Research Council’s 2011 report, “Assessing the Requirements for Sustained Ocean Color Research and Operations.” The purpose of the NOCCG is to keep members up to date about developments for satellite ocean color. With membership that includes representatives from all the NOAA line offices, NOCCG holds monthly meetings and an informational seminar, advertised widely both within and outside of NOAA, especially to the US ocean color community.

The NOAA CoastWatch Seminars, begun in January 2022, feature two speakers per month from the NOAA CoastWatch Science or Application Team presenting information that will be of interest to NOAA CoastWatch Users and the entire CoastWatch Team.

Abstract: Phytoplankton play a central role in marine biogeochemical processes and ocean ecosystems, and satellite ocean color observations provide a powerful means of monitoring their variability through changes in optical properties of seawater. However, interpreting long-term signals from ocean color data remains challenging due to the strong influence of natural variability and measurement uncertainties. In this seminar, we introduce an analysis framework that integrates long-term environmental records with multi-decadal satellite ocean color observations to better separate persistent signals from dominant modes of natural variability. By combining complementary datasets and applying signal-separation techniques, this approach enables a clearer examination of long-term changes in ocean optical properties without relying on short-term fluctuations.We discuss how variations in light absorption and scattering"linked to changes in phytoplankton and dissolved constituents"can be systematically examined using sustained satellite observations. Rather than focusing on specific regional outcomes, the emphasis of this seminar is on the methodological approach, data consistency, and the implications for long-term monitoring. This work highlights the importance of continuous, well-calibrated satellite ocean color records as an essential component of operational ocean monitoring systems and their applications to ecosystem and fisheries-relevant studies.
