In 1900 the Royal Navy signed a contract to build five ‘Holland’ class submarines. Entering service in 1903, these experimental boats were the Royal Navy’s first submarines, and over the next decade proved the value of the submarine as a weapon of war.

Developments in technology rendered the ‘Hollands’ obsolete and they were either sold for scrap or destined to be used for gunnery practice. HM Submarine No. 5 (the ‘Holland 5’) was en route to a naval yard when it slipped its tow and sunk in 1912. It lay undiscovered off the English south coast until accidentally found in 1995. Now protected by law, it has remained undisturbed on the seabed for almost a century.

In 2010 a Masters student from the School of Applied Sciences at Cranfield University and keen recreational diver, Duncan Harwood, decided to make the Holland 5 the subject of his dissertation.  More specifically, he wished to examine the rate of corrosion suffered by the wreck, and to consider the mechanisms and factors which may have affected that rate of corrosion.

Kerry Legislation Would Help Protect Historic Site of R.M.S. Titanic

April 3, 2012

WASHINGTON, D.C. – Senator John Kerry (D-Mass.) introduced legislation recently that would amend the R.M.S. Titanic Maritime Memorial Act of 1986 to protect the wreck site of the Titanic from salvage and intrusive research.

“We’re closing in on one hundred years this month since the tragic sinking of the Titanic that has captured the interest and imagination of people worldwide. I think it’s important to remember that this site on the floor of the Atlantic is a place where so many went to their deaths. It’s hallowed ground, not just some underwater area to be poked at or damaged for commercial reasons,” said Sen. Kerry. “This bill provides the authority necessary to help ensure the site of the Titanic is kept intact.”

One hundred years ago this April 15th, the R.M.S. Titanic sank on its maiden voyage. Shortly after the Titanic was discovered in 1985, Congress enacted the R.M.S. Titanic Maritime Memorial Act of 1986.  The 1986 Act specifically directed the Secretary of State to negotiate an international agreement to designate the Titanic an international maritime memorial and for research, exploration, and salvage of the Titanic to be consistent with relevant guidelines.

The *R.M.S. Titanic Maritime Memorial Preservation Act of 2012 *(S. 2279) would:

– Amend the 1986 Act by providing the Department of Commerce with the authority to protect the Titanic wreck site from salvage and intrusive research;

– Provide authority to monitor and enforce specific scientific rules to protect the public’s interest in the wreck site and collection;

– Propose the establishment of a Titanic Advisory Council, modeled on advisory councils that have been established under the National Marine Sanctuaries Act.

Patrimonio Cultural Subacuático y Maritimo en el Peru – Por Carlos E. Ausejo

August 16, 2011

El Centro Peruano de Arqueología Marítima y Subacuática (CPAMS), se formo a finales del año 2010 y esta formado actualmente por 4 miembros fundadores y una investigadora asociada, buscamos formar un equipo multidisciplinario aunque por el momento solo somos arqueólogos. El CPAMS tiene como objetivo promover la investigación científica arqueológica en ambientes marítimos subacuáticos, medios  fluviales, lacustres, sus zonas terrestres de  interacción así como el impacto del paisaje marítimo en el desarrollo de las sociedades a lo largo del tiempo. Buscamos difundir, proteger, preservar, conservar y poner en valor nuestro patrimonio natural y arqueológico distribuido en 2250 km del litoral pacífico, ríos, lagos costeros y de altura por medio de programas educativos para arqueólogos y talleres de sensibilización y desarrollo social.

La importancia de la arqueología marítima y subacuática en el Perú está en el extraordinario estado de conservación de materiales, que permite acceder a un tipo de información no registrada anteriormente (en el caso prehispánico) así como contrastar las fuentes escritas (época colonial y republicana).

Maritime and Underwater Cultural Heritage in Peru – By Carlos E. Ausejo

August 16, 2011

The Peruvian Centre for Maritime and Underwater Archaeology (CPAMS) was started at the end of 2010 and is currently made up of four founding members and an associate researcher. We intend to form a multidisciplinary team although at present we are still only archaeologists. The aim of the CPAMS is to promote scientific archaeological research in underwater maritime environments, rivers and lakes, their interaction areas on land as well as the impact that the maritime landscape has on society’s development over time. We seek to disseminate information on, protect, preserve, and conserve our natural and archaeological heritage that is distributed over the 2250km of the Pacific coastline, rivers, coastal and highland lakes and make it valued, by way of organizing educational programs for archaeologists as well as workshops on social development and awareness.

The importance of maritime and underwater archaeology in Peru lies in the extraordinary state of preservation of the materials which allows access to information not previously recorded (in the case of pre-Hispanic findings) as well as by contrasting findings with written sources.
