The Tjärnö Marine Laboratory is a marine science field station in Sweden. It is part of the University of Gothenburg and located on the island Tjärnö, Strömstad Municipality in the northern part of Bohuslän province.

TML was founded as a field station for university education in marine biology in 1963. During the first half of 1970s TML became manned year round, and scientists began to choose TML for their permanent place of work. The activities have expanded and diversified. 70 people now work permanently at TML.

Within 10 minutes by boat lies the Koster fjord, a 247 meter deep fissure fault between the Koster Islands and the mainland. It is in deep-water contact with the remaining Skagerrak, the North Sea and the Atlantic Ocean beyond, leading to oceanic salinity, 35 ‰, in the bottom water. This is the only true oceanic environment in Sweden, with the highest number of marine species in Sweden. Between 5000 and 10000 species are to be found in the Skagerrak, and more than 200 of them do not occur elsewhere in Swedish waters. For instance, cold water reefs of stony corals could be found.

Annually, about 500 university students, mainly from Gothenburg, attend courses at TML, lasting from one week to one term. A large proportion of the education is devoted to identification of marine algal and animal species. Other courses are more concerned with ecology, including training in experiments and investigations. Field education, on research vessels, in smaller boats and at the shore, are common.

The major research programs are directed towards marine ecology, presented under six programs – marine chemical ecology, evolution and genetics, biodiversity, biohydrodynamics, fishery biology and aquaculture, and integrated coastal zone management. Most scientists at TML belong to the Department of Marine Sciences at the University of Gothenburg.

TML is a resource for regional industry, decision-makers and authorities, and gives support for the development of research-based marine innovations and business projects.

At TML anyone can book guided tours and beach excursions. During summer season the public also can visit the aquarium, listen to popular science lectures and participate in excursions with research vessel.

Marine biology Scientific study of organisms that live in the ocean

Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

Underwater habitat Human habitable underwater enclosure filled with breathable gas

Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping. In this context, 'habitat' is generally used in a narrow sense to mean the interior and immediate exterior of the structure and its fixtures, but not its surrounding marine environment. Most early underwater habitats lacked regenerative systems for air, water, food, electricity, and other resources. However, some underwater habitats allow for these resources to be delivered using pipes, or generated within the habitat, rather than manually delivered.

National Oceanography Centre, Southampton

The National Oceanography Centre Southampton (NOCS) is a centre for research, teaching, and technology development in Ocean and Earth science. NOCS was created in 1995 jointly between the University of Southampton and the UK Natural Environment Research Council and is located within the port of Southampton at a purpose-built dockside campus with modern facilities. In 2010 the University and NERC components demerged, and the NERC-managed component became the National Oceanography Centre. The two components of NOCS continue close collaboration through the jointly run Graduate School, shared research facilities and laboratories, complementary research groups, and many joint research grants and publications. The University component “Ocean and Earth Science, National Oceanography Centre Southampton” (OES) is part of the Faculty of Environmental and Life Sciences, (FELS). It was ranked 46th in the world for Earth and Marine Sciences by the QS World University Rankings in 2019.

Aquatic science is the study of the various bodies of water that make up our planet including oceanic and freshwater environments. Aquatic scientists study the movement of water, the chemistry of water, aquatic organisms, aquatic ecosystems, the movement of materials in and out of aquatic ecosystems, and the use of water by humans, among other things. Aquatic scientists examine current processes as well as historic processes, and the water bodies that they study can range from tiny areas measured in millimeters to full oceans. Moreover, aquatic scientists work in Interdisciplinary groups. For example, a physical oceanographer might work with a biological oceanographer to understand how physical processes, such as tropical cyclones or rip currents, affect organisms in the Atlantic Ocean. Chemists and biologists, on the other hand, might work together to see how the chemical makeup of a certain body of water affects the plants and animals that reside there. Aquatic scientists can work to tackle global problems such as global oceanic change and local problems, such as trying to understand why a drinking water supply in a certain area is polluted.

Hotspot Ecosystem Research and Mans Impact On European Seas International multidisciplinary project that studies deep-sea ecosystems

Hotspot Ecosystem Research and Man's Impact On European Seas (HERMIONE) is an international multidisciplinary project, started in April 2009, that studies deep-sea ecosystems. HERMIONE scientists study the distribution of hotspot ecosystems, how they function and how they interconnect, partially in the context of how these ecosystems are being affected by climate change and impacted by humans through overfishing, resource extraction, seabed installations and pollution. Major aims of the project are to understand how humans are affecting the deep-sea environment and to provide policy makers with accurate scientific information, enabling effective management strategies to protect deep sea ecosystems. The HERMIONE project is funded by the European Commission's Seventh Framework Programme, and is the successor to the HERMES project, which concluded in March 2009.

History of marine biology Aspect of history

Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity. The earliest studies of marine biology trace back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition. The first recorded observations on the distribution and habits of marine life were made by Aristotle.
