Dear Coastal High-Frequency Radar (HFR) Communities of Practice and Interest,

Since I know many of you have oceanographic interests beyond HFR, I wanted to bring to your attention that the United States' National Science Foundation (NSF) has published a Dear Colleague Letter (DCL), requesting input on NSF-led ocean observing priorities.  Please see the DCL NSF 26-024 here, which was published today for more details.  Input is requested by September 30, 2026.

This follows NSF's initial plans to shut down much of the Ocean Observatories Initiative (OOI).  On June 18, NSF announced that they would pause these plans while requesting public input on the value of NSF ocean observing.  In addition to OOI, NSF investments in ocean observations include mid-scale infrastructure (e.g., GO-BGC Argo program, Cascadia Offshore Subduction Zone Observatory), and individual research projects that provide time series and longer-term observations.

Feel free to disseminate through your channels.

V/R,
Brian

Dear Oceanographic High-Frequency Radar (HFR) Communities,

Please see the reminder below regarding the Ocean Radar Conference in Asia-Pacific (ORCA-2026) and its International Summer School on Oceanographic Radars in Marine Science (ISSOR-2026).  Abstracts are due by the end of the week (September 5, 2026).


P.S.—This announcement may reach you via several HFR community distribution lists, so my apologies if you receive duplicate messages.  Please feel free to share this call for abstracts with your networks too.


Best regards,

Brian

Dear members of scientific committee from Asia-Pacific region,
Dear Colleagues,

Please find below the third announcement of the Ocean Radar Conference in Asia-Pacific (ORCA-2026) and the International Summer School on Oceanographic Radar applications in marine sciences (ISSOR-2026).

The deadline for abstract submission is September 5, 2026.

The conference and the summer school will be hosted by the International Centre for Interdisciplinary Science Education (ICISE) in the city of Quy Nhon, Central Vietnam, on October 20–23, 2026.
Please visit the ORCA website for further information and to submit applications for these events
