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.

With these funding opportunities, the priorities will

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

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

When operating a marine vessel in winter, there are always more risks due to the increased likelihood of severe weather and dramatic, often unpredictable, fluctuations in conditions throughout a journey. If travelling is a necessity, boat owners and marine businesses should take no chances as the consequences can be severe should something go amiss.

Navigating choppy waters

In December 2018, a Scotland-bound ferry was hit by severe weather conditions in the North Channel. This caused six lorries and other vehicles to topple against each other and overturn, causing significant damage and crushing cars in the impact.

Fortunately, none of the ferry’s 52 passengers and 56 crew suffered any injuries, however, some were confined to their vehicles during the incident
