Sea-level Change Since the Ice Age

A project to reconstruct sea-level change history since the last ice age is being undertaken by NOAA's National Geodetic Survey (NGS), installing precise-positioning infrastructure and conducting fieldwork off the coast of Belize in Central America to assist the Smithsonian Institution. NGS will use this opportunity to conduct a series of simultaneous Global Navigation Satellite System observations on several islands.   This study is an attempt to reconstruct relative sea level for the past 10,000 years. The mangrove islands in Belize are ideally suited for this purpose, because they are tectonically stable and isolated from the influence of human activity, land-derived... (read more)

Marine Mapping for the North Sea

SeaZone is leading the Bringing Land and Sea Together (BLAST) Work Package 3 - The Marine and Coastal Reference Base. This Working Group addresses the needs of marine spatial planning, environmental protection, socio-economic development, risk management and mitigation, by delivering harmonised land and sea geographic datasets. This specific project is part of the BLAST project which contributes to the ‘The North Sea Regional Programme 2007 - 2013' (INTERREG IVB) led by Christian Byrith. SeaZone's main purpose of the project is for the development of Marine and Coastal Base Reference Information, or digital base map for the North Sea. There are... (read more)

Extreme Swath Survey: The Dead Sea

A future article in Hydro international will describe our recent multi-beam survey of the Dead Sea. This brief overview extols the virtues of renting a complete multi-beam system as opposed to owning one. The survey presented extreme challenges, overcome by the readiness of manufacturers to venture into unknown waters. Since 2001 we have been mapping Israel’s Mediterranean offshore using my 96-kHz EM1002 multi-beam. The Dead Sea had always been a desired target, but there were excessive problems in transferring the ship, and the system’s high-frequency attenuation. After reading about ELAC’s Seabeam 1050 used in our area by the Turkish Navy,... (read more)

Shipwreck Monitoring in the North Sea

Surveyors Discover World War One Submarine
In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its homeport of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine. In order to guarantee nautical depths, the Rijkswaterstaat survey department runs an annual seabed monitoring programme. In July 2019, research vessel MS Arca left its home port of Scheveningen, the Netherlands, to conduct a shipwreck survey that included a World War One submarine.  As an executive agency of the Dutch Ministry of Infrastructure and Water Management, Rijkswaterstaat facilitates smooth and safe maritime traffic in the Dutch North Sea. One of its activities is an annual seabed monitoring programme. Apart from a few deeper spots, the Dutch part of the North Sea is in general 35 metres deep, while the coastal... (read more)

Equal Sharing of Deep-sea Resources

Hydro international Interviews Secretary General Odunton
Deep ocean minerals are the future resources for the common heritage of mankind as other natural resources are becoming depleted. The International Seabed Authority is an autonomous international organisation that administers the exploration for and exploitation of the resources in the international seabed. As deep-sea mining is coming within reach, regulation and control of deep-sea resources is becoming even more important. Hydro international interviewed Mr Nii Allotey Odunton, Secretary-General of the International Seabed Authority (ISA) on the involvement of the ISA in deep-sea mining. In July 2012, you were reappointed as Secretary-General during ISA’s 18th Assembly. What does this re-election... (read more)

Glacier Subject of Study Sea-level Rise

A team of scientists from British Antarctic Survey (BAS) is to survey the largest glacier in the world, Pine Island Glacier in Antarctica, to understand how ice is being lost and its likely contribution to future sea-level rise. This week, a four-strong team (two scientists and two support staff) embarked on the journey from BAS Rothera Research Station on the Antarctic Peninsula to their remote field site on Pine Island Glacier in Western Antarctica where they will spend twelve weeks living in tents.   Pine Island Glacier is of great interest to scientists worldwide as it has been thinning at...

Follow Live Exploration of Deep-sea Volcanoes

Anyone with a computer or mobile online device can follow 35 international scientists, led by NOAA, as they explore seafloor volcanoes. The scientists are providing live video from the deep sea and describing their discoveries as they explore submarine volcanoes in the Western Pacific’s Lau Basin, centred between Samoa, Fiji and Tonga. A robot vehicle on the deep seafloor is sending to the research vessel and the worldwide web, live streaming video of lava landscapes and their exotic ecosystems. The expedition can be joined live online each day, weather permitting, until 25 September 2012 between 3PM and 3AM, Eastern Daylight... (read more)

Seminar on Business Consequences of Sea Changes

Longer-term gradual climate change represents an even greater business risk. How much will future supply chains, business operations and markets be impacted by changes in temperature, rainfall distribution, storm intensity and rising sea levels? With these questions in mind, a workshop 'Small Sea Changes, Big Business Decisions' is being held on 31 October 2007 to explore how enhanced understanding of the oceans improves weather and climate prediction, enabling better informed business decisions.   This workshop will address how a better understanding of the oceans can lead to better business decisions and thus have very tangible benefits. The organisers expect key... (read more)
