The New Zealand Oceanographic Institute (NZOI) was a department within the Division of Marine and Freshwater Science, as part of the Department of Scientific and Industrial Research (DSIR).
Named the New Zealand Oceanographic Institute in 1955 when the scope of the Oceanographic Observatory was broadened to include marine biology and geology. In 1982 the Institute merged with the Freshwater Section of Ecology Division and the divisional name was changed to Division of Marine and Freshwater Science. The Freshwater Section became the Taupo Research Laboratory and in 1980 the NZOI moved into premises at Greta Point, Wellington. The Institute became part of National Institute of Water and Atmospheric Research (NIWA) as part of the changes associated with the 1992 Crown Research Institute Act. [1]
James Brodie was a founding staff member of the Oceanographic Institute in 1954 and led it from 1958 until 1977 (he was Superintendent from 1954-1958). [2] He had joined the DSIR in 1945 and was involved in the postwar reconstruction of geophysical work that led to the formation of geophysics division in 1951. As assistant to the director he had particular responsibility for geophysical research and oceanography in what was to be come the oceanographic observatory. In 1954 he helped found the Oceanographic Institute, which he led from 1958 to 1977. [3] Brodie's own research centered on pleistocene geology and he published papers that laid regional foundations in fields such as carbon-dating deep ocean waters, ocean floor topography and coastal currents. It was rudimentary science, done by dropping thousands of cards into the sea and recording where they later ended up, but it gave the first cohesive picture of near- shore circulation of coastal waters. [4]
Brodie was succeeded by Desmond Hurley who was Director in the period 1977-1986. A biologist, Hurley trained in New Zealand as well as the University of Southern California. He brought in new management practices and was co-founder of the New Zealand Marine Sciences Society. [1] Hurley was succeeded by Ron Heath who held the directorship from 1986 to 1992. Heath was a physical oceanographer who produced a large body of work on tides and circulation around New Zealand including a number of studies of the unique tides of Cook Strait. [5] Notable among these studies was an examination of the tracks of cross-strait swimmers who were significantly affected by tidal currents. [6] Heath moved to a senior position at the University of Otago in 1994 and was replaced by Douglas Gordon, a fisheries manager who oversaw the transfer to a group within NIWA. Through much of this time, Dr Janet Grieve, a biological oceanographer whose personal research focused on marine taxonomy and biological productivity, was the most senior woman scientist.
The institute was the first multi-disciplinary marine sciences organisation to be formed outside the United States and Britain. Brodie initially found rooms in chilly Victorian offices above a dress shop at the parliament end of Lambton Quay. It wasn't until 25 years later in 1980 that NZOI moved into new purpose-built laboratories at Greta Point. This was 3 years after Jim Brodie had had to retire aged 57 because he had completed 40 years in the civil service. The building was named after him. The Brodie Building was one of a pair of buildings designed by Toomath Wilson Irvine Anderson Ltd. The institute library held vital expedition reports, some dating back to the 1800s, which continue to be a major asset to research on New Zealand's flora and fauna. [3]
Initially, NZOI chartered the ageing cargo-passenger island trader Taranui for two lengthy periods each year. On Taranui, ship's positions were fixed in much the same way that James Cook had used two centuries earlier. Sextant angles fixed positions relative to features ashore or, remote from land, from the sun and stars. After several cloudy days, a ship's position could have a margin of error of tens of nautical miles. Sample position required a further guess based on wire angle and drift. Taranui served oceanography through until the early 1970s. [7]
In 1972, the government bought a damaged but younger German freighter, converted its once refrigerated holds into laboratories and scientists’ accommodation, installed a high-resolution seismic sounder/profilers into its hull, and named her Tangaroa (a prior ship than the present Tangaroa ). [8] A punch-tape controlled transit satellite navigation system was installed, but position fixes could be many hours apart. She undertook 155 cruises, many to the tropics, until she was damaged in a storm in 1984 and sold for scrap. [3]
This first Tangaroa was replaced with a 20-year-old, German, custom-built research vessel, Meteor and renamed Rapuhia on arrival. Bow thrusters and active rudders enabled the ship to maintain station in almost any sea conditions. With the demise of DSIR in 1992, Rapuhia was sold for scrap, and oceanography returned for a while to chartered vessels until the availability of the fisheries research vessel RV Tangaroa .
The Institute produced around 1140 refereed research papers, 102 DSIR monographs, 160 charts of bathymetry, sediments, geological structure, ocean currents and animal distributions, 83 charts of lakes and 450 informational reports. A number of staff continued on as part of NIWA. [1]
Oceanography, also known as oceanology, sea science and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and seabed geology; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology.
The Tasman Sea is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about 2,000 km (1,200 mi) across and about 2,800 km (1,700 mi) from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who in 1642 was the first known person to cross it. British explorer Lieutenant James Cook later extensively navigated the Tasman Sea in the 1770s during his three voyages of exploration.
Cook Strait separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is 22 kilometres (14 mi) wide at its narrowest point, and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington.
The Woods Hole Oceanographic Institution is a private, nonprofit research and higher education facility dedicated to the study of marine science and engineering.
Pelorus Sound is the largest of the sounds which make up the Marlborough Sounds at the north of the South Island, New Zealand.
A research vessel is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters.
The National Institute of Water and Atmospheric Research or NIWA, is a Crown Research Institute of New Zealand. Established in 1992, NIWA conducts research across a broad range of disciplines in the environmental sciences. It also maintains nationally and, in some cases, internationally important environmental monitoring networks, databases, and collections.
Walter Heinrich Munk was an American physical oceanographer. He was one of the first scientists to bring statistical methods to the analysis of oceanographic data. His work won awards including the National Medal of Science, the Kyoto Prize, and induction to the French Legion of Honour.
David McNiven Garner was notable as a published research physicist, with a focus in physical oceanography and ocean circulation.
The following outline is provided as an overview of and introduction to Oceanography.
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.
William B. Curry is an American oceanographer who is the president and CEO of the Bermuda Institute of Ocean Studies (BIOS). He is known for studying historical climate and ocean circulation. Curry holds a Bachelor of Science in geology from the University of Delaware (1974) and a PhD in geology from Brown University (1980).
New Zealand has large ocean energy resources but does not yet generate any power from them. TVNZ reported in 2007 that over 20 wave and tidal power projects are currently under development. However, not a lot of public information is available about these projects. The Aotearoa Wave and Tidal Energy Association was established in 2006 to "promote the uptake of marine energy in New Zealand". According to their 10 February 2008 newsletter, they have 59 members. However, the association doesn't list its members.
James William Brodie was a New Zealand geologist, oceanographer and amateur historian and philatelist.
RV Tangaroa is a research vessel operated by the National Institute of Water and Atmospheric Research (NIWA) of New Zealand. It was purpose-built as a Deepwater Research Vessel for the then Ministry of Agriculture and Fisheries Research Centre at a cost of $27 million to replace the ageing GRV James Cook. It has a DNV classification of 1A1 and Ice 1C. It was transferred to the new National Institute of Water and Atmospheric Research in 1992.
