Oxford University researchers are playing a key role in the first systematic survey of ocean life in the Maldives, from the surface to 1,000 metres deep. This will enable the Maldivian government to develop conservation and sustainable development policies so that the oceans continue to protect and provide for the Maldivian people.
Taking place between 4 September and 7 October, the Nekton Maldives Mission will deploy two of the most advanced human-occupied submersibles, which make use of robotic and autonomous systems and more than a dozen research technologies. This will make it one of the most technically varied and advanced missions ever undertaken in the Indian Ocean.

Hydrospatial Information System
The UN Economic and Social Commission for Asia and the Pacific (ESCAP) has created a gateway to data portals, enabling people to access and download statistical information and filter it by specific SDG (ESCAP, 2019). From here, the Resource Watch, which provides hundreds of datasets on the state of the planet and human well-being, can be accessed (ResourceWatch, 2019).
Filtering the data by the world oceans will render dozens of layers containing relevant hydrographic, oceanographic, biological, shipping and other information that users can combine for their own analysis. This is an example of how
The US National Oceanic and Atmospheric Administration has announced that several funding opportunities for Marine Debris Removal are now available for 2022.

The program will make awards of up to US$56 million (~€56.1 million) and is aimed at combating marine debris across all the coastal areas of the US, Freely Associated States, Great Lakes and territories. The funding is aimed at projects with the following priorities:
- The first priority is the focus on large-scale projects that remove large debris like derelict vessels, fishing gear, and more. Successful applicants are expected to be able to deliver throughout all coastal and marine areas in the United States.
- The second priority focuses on how applications will implement proven interception technologies that have a proven track record in intercepting marine debris at shoreline, estuarine, coastal riverine, and urban environments.

An Update on the Main Innovations of the Past Years
By Huibert-Jan Lekkerkerk • December 11, 2020
While nautical charting mainly focuses on bathymetry and objects that form a hazard to shipping, offshore construction and dredging require sub-bottom information. There is nothing worse in any project than finding wrecks or unexploded ordnance (UXO) after construction has started. The detection of covered cables and pipelines is also an important survey objective. There have been some interesting innovations in this field over the past years and, while this article does not attempt to be exhaustive, it provides an overview of the various types of system available.
The Sub-bottom Profiler
The classic instrument for detecting bottom layers and sub-bottom objects is the sub-bottom profiler (SBP), or shallow seismic system. We distinguish the pinger, boomer and
