On the front cover of Hydro International January/February 2020 you can see a picture of the Weddell Sea in Antarctica. Onboard the research icebreaker Polarstern, scientists are deploying a CTD Rosette System to measure oceanographic parameters.
This issue of the leading worldwide magazine focusing on hydrography contains the following articles:
- Research Expedition to Map the Scottish Seabed
- Analysing Mean Sea Level Variations across the Strait of Hormuz
- Perspectives by Dawn Wright: How a Treasure Map Led Her to the Bottom
- Remote, Frozen, Critical and Changing: the Weddell Sea
- Digital Tool to Streamline Hydrographic Information
Scientific Challenges of the Weddell Sea
Located in the Atlantic sector of the Southern Ocean, the Weddell Sea generates extremely dense bottom water that spreads into all the world’s ocean basins, transporting oxygen, CO2 and other solutes. Everything that is added here is transferred into the abyssal oceans, including anthropogenic CO2. However, changes are taking place in the Weddell region that will have an impact on other oceans and on the global climate. Read on...
Mapping the Scottish Seabed
Newly developed 3D imaging technology has allowed scientists to map Darwin Mounds, a unique area of cold-water coral reefs off the coast of Scotland, to see whether it has recovered since being declared a Marine Protected Area sixteen years ago. Read on...
Simplifying Survey Reporting
Wouldn’t it be great to work on a hydrographic project without spending a lot of time looking for all the elements needed for a professional report? This was what Sanyal Sunil had in mind when he developed SURge, a digital tool to simplify survey reporting. Read on...
Mean Sea Level Variations across the Strait of Hormuz
When using GNSS as a geodetic and topographic height survey technique, the GNSS-based ellipsoidal heights must be transformed into orthometric (‘levelling’) heights using the geoid-ellipsoid separation (‘geoid heights’), but these are not accurately known in all countries. Emirates Defence Industries Company (EDIC) and Fugro recently embarked on modernizing the geodetic and hydrographic infrastructure of the Emirate of Sharjah in the United Arab Emirates (UAE). Using GNSS, levelling and gravimetry, an accurate local geoid model was developed. This allowed analysis of the fine Mean Sea Level (MSL) variations along and between the Arabo-Persian Gulf and the Oman Sea on both sides of the Strait of Hurmuz. Read on...
