S-121: A New Standard for Maritime Limits and Boundaries

The fundamental importance of maritime zones and other marine areas is underscored in the United Nations (UN) Sustainable Development Goal 14, which aims to conserve and sustainably use oceans, seas and marine resources. Maritime Limits and Boundaries (MLB) circumscribe and define these maritime and marine spaces, and incorporate the applicable Rights, Responsibilities and Restrictions (RRR). S-121, the widely anticipated marine data standard, provides a new open access method for providing and exchanging digital representations of MLBs. Maritime Limits and Boundaries and Ocean Governance Efficient and sustainable ocean governance requires, among other things, accessible high-quality data and information to support its decision-making...

Automated Depth Area Generation for Updating NOAA Nautical Charts

NOAA’s Marine Chart Division (MCD) is currently revising production efforts using an ‘ENC-first’ approach to provide seamless and tiled geographic coverage. Currently, ENC production workflows within MCD require cartographers to manually manipulate data in the Nautical Information System (NIS) to update navigation products. This MCD addressed this production bottleneck by developing a tool to derive depth area, contour and sounding vector data directly from gridded raster bathymetry surface data. Production of Electronic Navigational Charts (ENCs) Over the past decade, automation of data compilation procedures within National Oceanic and Atmospheric Administration’s (NOAA’s) Office of Coast Survey (OCS) and MCD (responsible for...

Where Do We Map Next?

A GIS Case Study from the Atlantic
Mapping the world’s oceans would benefit from a prioritization strategy. GIS-based analysis is helping to identify potential target areas for future mapping efforts in the North Atlantic Ocean. Mapping the world’s oceans is a tremendous task that would benefit from a prioritization strategy. In this article, an in-depth presentation of one such approach is given: GIS-based analysis that identifies potential target areas for future mapping efforts in the North Atlantic Ocean. The authors state that more knowledge about the seafloor could be significantly accelerated if all bathymetric data were publically available. A Worldwide Data Gap Bathymetry underpins the safe, sustainable... (read more)

Anne-Cathrin Wölfl

Anne-Cathrin Wölfl is a postdoctoral research associate in the research division Dynamics of the Ocean Floor at the GEOMAR Helmholtz Centre for Ocean Research Kiel in Germany. She received a PhD from the University of Hamburg in 2015 working on fjord systems in maritime Antarctica. Her work now focuses on investigating the deep ocean floor by hydro-acoustic means including the collection, processing, visualisation and interpretation of high-resolution bathymetry data. She has a passion for exploring data using multivariate data analysis and GIS; and further advocates for marine conservation, open science and data sharing. (read more)

Understanding Deep-sea Minerals and Ecosystems

Ifremer’s Explorations and Research
France and Ifremer have had a long involvement in the discovery and study of deep-sea mineral resources and their associated ecosystems. With a rather unique position in the marine research landscape, Ifremer is actively involved in the deep sea, both as a contractor with the ISA and as an integrated marine science research institute. The HERMINE 2017 exploration cruise on the French polymetallic sulphides exploration contract is an example of combined mineral exploration and scientific investigations. In the seventies, France was amongst the pioneer nations that discovered the metal-bearing hydrothermal sources and explored the polymetallic nodule deposits in the Clarion... (read more)

Coast Guard Using Sensors and Satellite Imaging to Track Vessels in Real Time

Esri has announced that Argentina's coast guard, Prefectura Naval, and Aeroterra S.A. have partnered to implement Esri's ArcGIS platform for a real-time tracking system. The new system, called Guardacostas Pro, uses a combination of satellite imaging and signal processing to monitor vessels for illegal activities such as drug smuggling and fish poaching in the coastal waters of Argentina’s exclusive economic zone (EEZ). As Argentina's coast guard, Prefectura Naval deploys patrol vessels, helicopters and aircraft spotters to protect its economic interests and to guard against the decline of its fishery industry. This year, the Guardacostas Pro system allowed Prefectura Naval to... (read more)

Hydrographic Surveying Supporting the Search for MH370

Last week, the MH370 Safety Investigation Report was presented by the Ministery of Traffic of the Malaysian Government. On 8 March 2014, the  Malaysian Airlines aircraft went missing in the Indian Ocean. Since then, a big search operation has taken place aiming to track down the fuselage in the waters, but the aircraft was never found. The search gave, however, tons of additional data of the ocean floor to the underwater mapping community. Hydro International has followed the developments with great interest and below, you can find articles and news with great building blocks of oceanographic and hydrographic data. Increased-resolution Bathymetry... (read more)

Special Achievement in GIS Award for MH370 Search

Geoscience Australia has been awarded the 2018 Special Achievement in GIS Award (SAG) by Esri, the global leader in Geographic Information System (GIS) technology. In San Diego to accept the award as part of Esri's User Conference on 11 July 2018, Geoscience Australia Chief Scientist Dr Adam Lewis said that while the data were collected for the sole purpose of locating the missing aircraft, it was important to recognise that this is some of the first high resolution data of this region, and will be valuable to the scientific community. The SAG award recognises the international benchmark Geoscience Australia set... (read more)

Mapping the Seafloor with Remote Sensing and Satellite Imagery

An Analysis of the Techniques and Benefits of These Methods
70% of the Earth is covered by water, but so far just 7% of it has been surveyed (Mars, Venus and the Moon are better surveyed). Hydrography as a science has changed dramatically since the first measurements were made by Alexander Dalrymple and James Cook with lead lines and sextants. Singlebeam echosounders were invented in the 1920s – a technology still used today for mapping the seafloor. This method of using echosounders can produce very high-resolution bathymetric data but the high operational costs and the slow working process make it economically unsuitable for covering large areas. However, with the ongoing expenses of... (read more)

ABPmer Gives Free Access to Metocean Data and Statistics

ABPmer, a recognised authority in metocean data services, has recently launched its Global Data Explorer providing instant access to free metocean data and statistics. Using the data explorer enables users to discover the world’s wind and wave climate, obtain free metocean analysis and download key metocean statistics. The company took the decision earlier this year that having expanded SeaStates, its metocean information service, to provide global coverage that it would harness the power of webGIS technologies and provide direct access to some of its datasets. Look-see of ocean characteristics The information available gives users a “look-see” of ocean characteristics that could be very useful... (read more)
