Offshore Environmental Surveys

Introduction to UK Legislation and Guidelines
This is a brief introduction to UK offshore marine environmental survey legislation and guidelines, written from a fairly narrow perspective: that of a contractor providing such survey services to the oil & gas industry. Legislation requires environmental surveys of the North Sea but the extent and definition of these is open to interpretation, with quite a variety of standards and guidelines to choose from or ignore. Legal FrameworkUK environmental legislation transposes European Community (EC) directives on the environment. The prime EC directives are Council Directive 92/43 ‘on the Conservation of Natural Habitats and of Wild Fauna and Flora’ (‘the Habitats... (read more)

As it Was

by the Old Hydrographer
Olaus Magnus, a Swedish Catholic priest, had for some years been employed collecting funds for the Church in the far north. During his extensive travels he made copious notes and sketches concerning the inhabitants and their way of life, the flora and fauna and even the denizens of the adjacent seas. With the advance of Lutheran creed across Scandinavia, and its acceptance by King Vasa, Olaus retired to Italy to spend the rest of his life compiling, with the aid of his numerous notes and sketches, a massive map of Scandinavia and in writing a prodigious illustrated history of the...

Ireland's First Smart ROV

The Mobile & Marine Robotics research Centre, University of Limerick
The Mobile & Marine Robotics Research Centre describe their motivation for building their own Smart ROV based on previous survey experience and the preparations they are now undertaking to integrate new survey and navigation control technologies for this month The Mobile & Marine Robotics Research Centre (MMRRC) has grown out of the Department of Electronic & Computer Engineering at the University of Limerick (Ireland), with research, development and commercialisation funding from a variety of government and semi-state bodies.   Underwater Technology Since 2003 the MMRRC has been developing novel underwater technologies to aid high-resolution sonar and video seabed imaging, near...

The Survey of the Philippine Islands

Following the Spanish–American War, the Philippine Islands became a US Protectorate. Consequently, the US Coast and Geodetic Survey commenced providing this vast archipelago with modern nautical charts. An assignment in the Philippines was the great, defining experience of a lifetime for many young officers and four future directors of the Coast and Geodetic Survey had at least one tour of duty there. A look into Pacific life is presented on these pages. Nothing in their American background prepared the Coast and Geodetic Survey (C&GS) for the kaleidoscopic melange of cultures, terrain, flora and fauna that was the Philippine Islands. Over...

Some Early German Contributions to Oceanography

The names Augustus Petermann, Victor Hensen, Carl Chun, Fritz Spiess, Alfred Merz, and Gunter Dietrich are hardly household names. Even today their names are little known in the geographic, oceanographic, and hydrographic communities which they served so well. They were all part of a thriving German geographic and oceanographic community which made many advances in the three generations between the late 19th century and the advent of the Second World War. Their work is little known except to a few science historians and interested oceanographers, primarily as a result of the World Wars. Collectively, their ships had such names as... (read more)

The Siboga Expedition

Biological, Hydrographic and Oceanographic Accomplishments in the Late 19th Century
The Indonesian Archipelago is one of the world’s most beautiful archipelagoes. Home to over 17,000 islands, mountains rising to over 5,000 metres including over 70 historically active volcanoes, fabled spices, and a rich flora and fauna, Indonesia has beckoned fortune seekers and naturalists for centuries. The shores of its far-flung islands are bathed by two oceans and at least eleven separate seas making it also a challenging area for hydrographers. In the late 19th century, Indonesia was administered by the Dutch and known as the Dutch East Indies. The terrestrial flora and fauna of the area was fairly well known... (read more)

Robotic Glider to Map Moreton Bay Impacts

An AUD200,000 CSIRO coastal glider is bound for Queensland, Australia, to be deployed in Moreton Bay to investigate the impact of the recent flooding on marine ecosystems. Dr Andy Steven from CSIRO's Wealth from Oceans Flagship says the glider's deployment is part of a research program to monitor the extent of the flood plume into Moreton Bay and assess its effects. Dr Steven said that this disastrous flood provides CSIRO with a rare opportunity to understand how the marine ecosystems respond to massive inputs of fresh water and sediments. "The glider will generate three-dimensional maps illustrating the impact of the... (read more)

World’s Biggest Submarine Pipeline Plough Put to Work

The world’s biggest submarine pipeline plough, PL3, arrived on 8th February in the Baltic Sea on the deck of mother ship Far Samson. The subsea plough will be used to entrench the Nord Stream Pipeline in Swedish and Danish waters. Lowering of the pipeline below seabed level using PL3 ensures that the pipeline will remain stable in its position throughout its lifetime. Ploughing of the first pipeline is scheduled to be performed at several locations along the pipeline route between early February and mid-March, 2011.     Model simulations have shown that ploughing will have no significant impact on flora...

Green Air Pushes

Autonomous Unmanned Surface Vessel
Bathymetry is largely used for measuring ocean and sea depth but there are also many other different applications in lakes, dams, rivers and fresh water basins. Logistic constraints as well as risks and economic issues make bathymetric measurement, especially in fresh water, not a simple task. This, in fact, normally implies the use of a motorised craft of a certain dimension, capable of accommodating the helmsman and at least one operator of the measuring system plus the relevant equipment. Often boats have to be transported to difficult to reach places or have to operate in sites hazardous for humans such... (read more)
