The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...

2018年11月5日 · When marine organisms eat and grow they capture and store carbon, termed blue carbon. Polar seas have extreme light climates and sea temperatures. Their continental shelves have amongst the most intense phytoplankton (algal) blooms. This carbon drawdown, storage and burial by biodiversity is a quantifiable ‘ecosystem service’.

2024年10月7日 · The use cases – compiled as part of the ‘Wind in the Sails (WITS)’ project – aim to address pressing global issues such as climate change mitigation, marine biodiversity protection, and Blue Economy development. They also ensure that seabed mapping efforts are targeted to support ocean sustainability, policy development, and economic ...

Blue carbon is captured and/or stored in coastal and marine habitats including saltmarshes, seagrass meadows, kelp forests, biogenic reefs and in sediments such as mud on the seabed, as well as microscopic algae in our seas.

2024年4月12日 · Blue carbon has huge potential to provide ocean-based solutions to help mitigate climate change, and thankfully, at the global scale at least, these losses have slowed in recent years.

2025年2月24日 · Shortly after, the Nippon Foundation-GEBCO Seabed 2030 Project announced a new partnership with the World Ocean Council (WOC), a leading organization in the global blue economy. This collaboration aimed to further advance the mission of mapping the entirety of the world’s ocean floor.

2024年9月19日 · UK seabed habitats could capture up to 13 million tonnes of organic carbon every year – almost three times the amount sequestered by the UK’s forests. Seabed disturbances, including from bottom trawling and offshore development, are identified as threats to blue carbon stores, as nature charities call for stronger protections for UK seas.

2021年1月1日 · This chapter explores the importance of seafloor mapping to the new blue economy and the private sector’s role in making these critical datasets more accessible worldwide. It starts by decribing a general lack of good bathymetry data globally, and notes how this deficiency inhibits sustainable ocean development.

2020年6月24日 · The shape of the seabed is a crucial parameter for understanding ocean circulation patterns that distribute heat between the tropics and poles. Bathymetry data also supports detailed assessments of future sea-level rise, as well as tsunami and storm surge modelling to provide the basis for actions to protect coastal communities.

Thousands of metres of water hide the seabed from the satellites we use to map the earth’s surface. To overcome this unique challenge, the Seabed 2030 project crowdsources data collection by enlisting the support of commercial boats, governments and research institutes, and supporting the development of autonomous vehicles that scan the ocean ...
