Project SeaSense

For scientists

Sailboats go where fixed stations don't, and they come back to the same waters week after week. Our work is turning that into data you can trust: every reading tied to a known instrument, and every boat checked against reference stations and against other boats.

Endorsed by the UN Ocean Decade

UN Decade of Ocean Science for Sustainable Development 2021–2030

Project SeaSense is an endorsed Decade Project of the UN Decade of Ocean Science for Sustainable Development (2021–2030).

The Ocean Decade brings together the science we need for the ocean we want. Our part: turning the boats already at sea into a coastal observing network, with open data for anyone working on the ocean.

About the Ocean Decade

Proclaimed in 2017 by the United Nations General Assembly, the UN Decade of Ocean Science for Sustainable Development (2021-2030) ('the Ocean Decade') seeks to stimulate ocean science and knowledge generation to reverse the decline of the state of the ocean system and catalyse new opportunities for sustainable development of this massive marine ecosystem. The vision of the Ocean Decade is 'the science we need for the ocean we want'. The Ocean Decade provides a convening framework for scientists and stakeholders from diverse sectors to develop the scientific knowledge and the partnerships needed to accelerate and harness advances in ocean science to achieve a better understanding of the ocean system, and deliver science-based solutions to achieve the 2030 Agenda. The UN General Assembly mandated the Intergovernmental Oceanographic Commission (IOC) of UNESCO to coordinate the preparations and implementation of the Decade.

What we offer

  • Use the data

    Coastal surface pressure, depth and water temperature from moving boats, with quality information attached.

  • Shape the network

    Tell us what you need measured, and where. Blauwe Long 2027 is being planned now.

Where we are

Short version: the idea works at sea. Now it needs more boats.

  • Air pressure

    Ready

    Weather-station quality.

  • Depth and water temperature

    Ready

    Usable, especially in shallow coastal water.

  • Water quality

    In development

    Salinity and pH pick up real gradients; the probes don't yet last at sea, and oxygen isn't there yet.

  • Wind

    In development

    Collected, but not yet good enough under sail.
