SOLAS-OCB Sea Surface Microlayer

2023 January 27 & February 10Luc Deike (Department of Mechanical and Aerospace Engineering, Princeton University, United States) - Ocean spray aerosols generation: From breaking waves to bursting bubbles

Andrew Wozniak (School of Marine Science and Policy, University of Delaware, United States) Untargeted, high resolution mass spectrometry for characterizing surfactant organic matter in the sea surface microlayer

Sarah Brooks (Department of Atmospheric Sciences, Texas A&M University, United States) - Influence of the sea surface microlayer composition on cloud formation
The sea surface microlayer is an important interface controlling the transfer of energy, material and gases between the oceans and the atmosphere, and has been a primary focus of the SOLAS programme since its inception. The five SOLAS themes all include processes that affect and are affected by the sea-surface microlayer, including marine ecology, photochemistry, free radical/thermal chemistry, greenhouse gases and gas exchange, primary aerosol production, and atmospheric deposition. Therefore, the sea surface is one of five cross-cutting themes explored in the new United States SOLAS Science Plan, which was released in 2021. This seminar highlights some recent work at this exciting interface.

Organizing Intercalibration Efforts for BioGeoSCAPES: A Panel Discussion

2023 January 25Maite Maldonado – Introduction and Webinar Goals

Daniel Petras and Jeffrey Hawkes – Metabolomics Intercalibration update

Adrian Marchetti – US Nucleic Acids Intercalibration Workshop Results

Mak Saito – Ocean Metaproteomics Intercomparison Update and Sampling Material

Luke Thompson, Alyse Larkin and Harriet Alexander – BioGoSHIP Nucleic Acids Intercomparison

Daniele Iudicone – Perspectives from AtlantEco/Tara

Julie LaRoche – Rates Measurement Intercalibration

Open Plenary Discussion
Producing data that can be effectively compared across space and time is a critical aspect of developing a collaborative international microbial biogeochemistry program. Intercalibration activities involving validation of precision and accuracy and development of intercomparison standards are foundational to the production of interoperable data. With BioGeoSCAPES aiming to launch mid-decade, further progress must be made to ensure high-quality data collection. This virtual panel will include perspectives from a variety of communities (nucleic acids, metabolomics, proteomics, rates) and encourage brainstorming through small group discussions. This panel discussion initiates important discussions and community-building in preparation for an international BioGeoSCAPES science planning workshop in Woods Hole, MA USA (tentatively scheduled for Fall 2023).

Q&A and open discussion
A community meeting (a repeat of a recent Ocean Sciences Town Hall Meeting to enable broader participation) to learn more about a new NSF EarthCube-funded Research Coordination Network for Marine Ecological Time Series (METS-RCN) tasked with bringing together members of the oceanographic, data science, and informatics communities to build consensus on key components of a FAIR (Findable, Accessible, Interoperable, Reusable) data model for METS, including common vocabularies, metadata reporting standards, and data citation practices; engage broader METS data users (e.g., modelers, educators, decision makers) to facilitate broader applications of METS data; and build community capacity for METS data analysis, statistical methods, and data-model integration. This town hall meeting will also highlight a concurrent EuroSea-funded project led by members of the RCN leadership team focused on developing a pilot biogeochemical time series data product to help visualize spatial patterns and trends across ocean basins.METS-RCN

OCB-US CLIVAR Ecological Forecasting Workshop webinar

2022 January 11Simone Alin (NOAA PMEL)The Olympic Coast as a sentinel: Integrated social-ecological vulnerability assessment and co-developing ocean resource management tools with tribal and state managers

As part of a regional vulnerability analysis, our team synthesized existing oceanographic data sets and model projections to understand how the frequency, duration, and severity of ocean acidification and co-stressor (warming, hypoxia) conditions may change between now and the end of the century and affect biological resources. Meanwhile, social scientists worked with Washington's coastal treaty tribes to identify the marine species of highest cultural and subsistence value to the tribes and to assess social vulnerability of tribal communities to changing ocean conditions. Ultimately the oceanographic synthesis and projections will inform tribal adaptation actions. On a related project, many of the same team worked with state and tribal managers to develop tools useful to managers of the Dungeness crab fishery in state and tribal fishing areas. In this talk, I will briefly describe scientific results and products of our collective work, but will focus as much on the challenges and lessons learned from working with this diverse team, consisting of natural and social scientists (working across academic institutions; federal, state, and tribal agencies) and tribal community members.
