The Ocean Sciences Meeting (OSM) is the flagship conference for the ocean sciences and the larger ocean-connected community. Every two years, the Ocean Sciences Meeting unifies the oceans community to share findings, connect scientists from around the world, and advance the impact of science. The Ocean Sciences Meeting 2024 is co-sponsored by the American Geophysical Union (AGU), the Association for the Sciences of Limnology and Oceanography (ASLO), and The Oceanography Society (TOS).

We are pleased to inform you about the upcoming International Digital Twins of the Ocean Summit 2023, which will be held in Xiamen, China on 9-12 November 2023. Taking the great arena of 2023 World Ocean Week in Xiamen, the DITTO Summit 2023 will be co-organised by the Fujian Ocean Innovation Center and State Key Laboratory of Marine Environmental Science (Xiamen University), and to gather global participants with themes focusing on sharing the latest knowledge about DTOs and discussing future actions on advancing and applying them. The abstract submission's deadline is extended to 20 August 2023. For further details please read the Third Announcement.

We are thrilled to inform you that Ocean Acidification Week will be back in 2023. GOA-ON’s OA Week event is a virtual multi-day forum to highlight ocean acidification research for sustainability initiatives around the world. This event features plenary talks, thematic sessions featuring 3-5 talks, and community discussions. It is free and open to everyone for participation. OA Week is a great opportunity to share your research or ideas around the OA community with a wider audience. The organizers welcome all ideas for topics and sessions. If you are interested in participating in OA Week 2023, please fill out this registration survey to indicate your interest in organizing, facilitating, proposing or presenting any of the sessions before 11 August 2023.

We would like to let you know about the upcoming SOLAS seminar on "Halogen chemistry: from ocean to stratosphere" hosted by SOLAS Early Career Scientist Committee (ECSC), International Global Atmospheric Chemistry (IGAC), and Early Career Scientific Steering Committee (ECSSC). The seminar is scheduled for 25 July 2023 at 12:00 UTC and will be held on ZOOM platform. To attend the seminar please register here.

We would like to let you know about the upcoming ocean deoxygenation webinar organized by the Global Ocean Oxygen Network (IOC Expert Working Group GO₂NE). The 21st webinar will take place on 26 July 2023 at 13:00 CEST. The webinar will feature presentations by a more senior and an early-career scientist, 20 minutes each followed by 10 minutes moderated discussion sessions. Please register here.

The 3rd edition of the "Instrumenting our ocean for better observation: a training course on a suite of biogeochemical sensors" took place on June 5-17, 2023, and was hosted by Kristineberg Marine Research Station in Sweden.

The training course was attended by 28 very motivated early-career scientists from different parts of the world selected from one hundred applications. For almost two weeks 25 dedicated instructors affiliated with universities, research institutions, or sensor-producing companies, were conducting the lectures and workshops sharing their practical expertise. During the hands-on sessions, the attendees could practice sensor usage in marine environments.

We are pleased to let you know about the upcoming GOA-ON's webinar co-hosted by the North American Hub on "Global Ocean Acidification Indicators and the NOAA strategy for Carbon Dioxide Removal Research". The webinar will take place on 2 August 2023 at 15:00 UTC. Registration form is available here: https://unesco-org.zoom.us/webinar/register/WN_elOwglVnRgu2IgbTJIFjkg#/registration 

We are pleased to inform you about the 8^th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP) that will be organized by WMO and hosted by the Swedish Meteorological and Hydrological Institute (SMHI) in Sweden, at the SMHI main office in Norrköping, on 27-30 May 2024. 

This upcoming 8th Workshop will focus on assessing the impacts of various observing systems in all Earth system domains on NWP. However, the scope will be extended to also encompass the impact assessment of the various observing systems, to other Earth system applications. We strongly encourage our community to look through the identified science questions relevant to marine biogeochemistry, especially S1.12-16 related to surface-based observing systems, and S2.9 related to space-based observing systems, and consider submitting an abstract. The abstract submission is open until 15 December 2023.

The Workshop will be held in a hybrid format (in-person and remote participation will be enabled), and will be conducted in English. Participation in the workshop is free of charge. There is no workshop fee. For more information, please visit the WMO website.

This is to let you know about the International Underwater Glider Conference scheduled on 10-14 June 2024 at Reveljen in Gothenburg, Sweden. This will be the 9^th EGO meeting, supported by the OceanGliders and the EuroGOOS Glider Task Team. The International Underwater Glider Conference aims to bring together leading researchers, innovators, and experts from around the globe to exchange knowledge, share discoveries, and foster collaborations in the exciting realm of underwater gliders. The conference promises to be an engaging platform for sharing insights, addressing challenges, and shaping the future of this field.

The call for abstracts will open in September 2023. If you have any questions, do not hesitate to contact This email address is being protected from spambots. You need JavaScript enabled to view it. or This email address is being protected from spambots. You need JavaScript enabled to view it.
