Great Barrier Reef Temperatures “Alarmingly High”, Bringing Unprecedented Heat Stress to Corals

February 9, 2022

A new paper by the NOAA Coral Reef Watch (CRW) program, an initiative supported by the ESSIC-administered Cooperative Institute for Satellite Earth System Studies (CISESS), shows that Australia’s Great Barrier Reef (GBR) started the 2021-2022 summer season with more accumulated oceanic heat stress than ever before in the satellite record (i.e., 1985 to the present). As of December 14, 2021, NOAA CRW’s daily global 5km satellite coral bleaching heat stress products indicated that instantaneous heat stress and accumulated heat stress over the prior 12 weeks were unprecedented on the GBR.

ESSIC/CISESS at AMS Conferences

February 9, 2022

The American Meteorological Society (AMS) Annual Meeting was held virtually this year from January 23 to 27. Simultaneously, AMS held a number of specialized conferences and symposiums, focusing on topics including hydrology, climate variability and change, and atmospheric chemistry. ESSIC/CISESS scientists contributed a large number of talks and posters at the event. Talks included:

Santiago Gassó is one of the co-authors in the recently released science plan by the US Surface Ocean – Lower Atmosphere Study (SOLAS), a global and multidisciplinary research project established to provide international science coordination and capacity building. SOLAS is focused on understanding the key biogeochemical-physical interactions and feedbacks between the ocean and atmosphere that are critical elements of climate and global biogeochemical cycles.

Congratulations to Isaac Moradi, Newly Elected Member of the University State Senate

February 9, 2022

ESSIC/CISESS Research Scientist Isaac Moradi has been elected to the University State Senate as one of the Professional-Track Faculty members. The University Senate, composed of faculty, staff, students, and administrators, is one of the largest and most influential governing bodies at the University of Maryland. As a member of the senate, Moradi will help advise the University President on campus policy matters and concerns, including education, budget, personnel, campus-community, long range plans, facilities, and faculty, staff and student affairs.

Innovative Use of Satellite Data Establishes Water Clarity Improvement at Restored Oyster Reefs

February 9, 2022

Ron Vogel, ESSIC senior faculty specialist, recently co-authored a NOAA Technical Memorandum with colleagues from NOAA’s National Marine Fisheries Service, titled “Using Satellite-Derived Total Suspended Matter Data to Evaluate the Impacts of Tributary-Scale Oyster Restoration on Water Clarity.” In the study, the team sought to explore whether large-scale oyster restoration in the Chesapeake Bay, on the order of 100s of acres, can produce improvements in water clarity that are measurable, and whether satellites can be a tool to help measure that change.

Using Bayesian Deep Learning to Improve Precipitation Retrievals

February 1, 2022

ESSIC/CISESS Scientist Veljko Petković co-authored a study on the application of new and emerging field of BDL concepts to mitigate problems associated with the accuracy of precipitation retrievals from satellite-borne passive microwave (PMW) radiometers, which was published in IEEE Geoscience and Remote Sensing Letters.

Jiang Leads International Effort to Create New Data Standard for Oceanographic Research

February 1, 2022

ESSIC/CISESS Scientist Li-Qing Jiang, who works on the Ocean Carbon Acidification Data System (OCADS) project at the National Center for Environmental Information (NCEI), coordinated a massive effort by the international community to develop a best practice data standard for discrete bottle-based chemical oceanographic data. The study, co-authored by ESSIC/CISESS Scientist Alex Kozyr and esteemed scientists at over 30 institutions in 10 countries, was published on January 21st in Frontiers in Marine Science.

CISESS Presents Two AMS Short Courses

January 26, 2022

Scott Rudlosky and Joseph Patton led an AMS short course titled “Accessing and Applying Geostationary Lightning Mapper Observations” on January 5 and 6. This two-part course introduced the GLM observations and imagery using GLM flash skeletons and gridded products used by the National Weather Service. Participants were shown how to access archived and real-time imagery before conducting a hands-on exercise illustrating their new-found skills. Additional information can be found at this link: Accessing and Applying Geostationary Lightning Mapper Observations.
