This dataset provides the boundary of New Zealand’s continental shelf, which is the area of seabed around a large land mass where the sea is relatively shallow compared with the open ocean. The continental shelf is the seabed and subsoil of the submarine areas that extend beyond the territorial sea of a coastal state throughout the natural prolongation of its land territory to the outer edge of the continental margin. In New Zealand’s case, the continental margin extends beyond the Exclusive Economic Zone in many places and the outer limits have been established on the basis of the recommendations of the United Nations Commission on the Limits of the Continental Shelf. Under UNCLOS, New Zealand exercises sovereign rights over the continental shelf for the purpose of exploring it and exploiting its natural resources. Note: The boundary includes, where applicable, the delimitation of the boundaries of the continental shelf with Australia under the treaty of 25 July 2004. The delimitation of the maritime boundaries in the north with Fiji, Tonga and possibly France in respect of New Caledonia, have yet to be settled by treaty.

A tide gauge was installed in November 1990 and has been in near continuous operation since. A 10 minute average of water depth was recorded each hour with hourly averages of wind speed and direction, air temperature and solar radiation. From 2000 the recording frequency was increased from every hour to every 10 minutes. From 2003 data is read every 10 seconds and an average value (from 60 readings) is calculated every 5 minutes and recorded. Barometric pressure was measured as well, starting in 2003, with six barometric pressure readings made between 2 and 3 minutes in the 5-minute interval and averaged and recorded with the tide value. Each year the rise and fall of the sea ice is observed over a 2 - 3 day period during a spring tide using GPS. These measurements are related to a tide gauge bench mark and the sea surface to enable the reliability of the tide gauge to be checked. The tide gauge data is archived by Land Information New Zealand. GET DATA: https://sealevel-data.linz.govt.nz/index.html?tidegauge=ROBT

In collaboration between the Korea Polar Research Institute and NIWA, an oceanographic mooring was deployed to the North of the Drygalski Ice Tongue (lat:-75.360767, lon:164.746467) on March 2020, and it was recovered on March 2022 (ANA12D research cruise).

The data set contains water temperature, salinity, and oxygen taken by CTD during three hydrographic sections perpendicular to the slope in the Western Ross Sea between Cape Adare and the Drygalski Trough. Data are in NetCDF. GET DATA: https://www.ncei.noaa.gov/archive/accession/0219916

CTD data collected during Marta Guerra's PhD project 'Foraging ecology of sperm whales at Kaikōura'. Time coverage: 30-May-2015 to 2-Jan-2018, including autumn/winter field season ('winter', May-July) and spring/summer field season ('summer', Nov-Jan), with a total of 3 winters and 3 summers. CTD casts collected daily (weather permitting) throughout the duration of each field season (each field season lasted typically 8 weeks). Spatial coverage: study area centered over the Kaikōura Canyon. Approximate area: from Kaikōura peninsula, extending out to 12 nautical mile offshore navigational limit to the East and Southeast, and extending 15 nautical miles from the Kaikōura peninsula to the South. CTD carried out over seafloor depths of c. 200m to c. 1500m. Measured variables: temperature, salinity, chlorophyll-a concentration. CTD depths: variable, down to a maximum of 550 m. Instrument type: Winter 2015 = CTD Seabird scientific SBE-19, with WET-Star fluorometer. Maximum depth = 100m. Sampling frequency = 4 Hz. All other seasons = CTD RBR-concerto, with Turner Designs Cyclops-7 fluorometer. Maximum depth = 550m. Sampling frequency = 4 Hz. Platform type: hand-hauling from 6m outboard-powered vessel 'RV Grampus'. Quality control: data were deleted from the processed files when there was a known malfunction with one of the sensors. The processed files also had the upcast deleted from them, as well as the measurements in air, and acclimatisation period at the surface (1 minute since submersion).

New Zealand is not immune to ocean acidification. The ‘Munida transect’ Time-series in sub-antarctic waters off Otago is the Southern Hemisphere’s longest-running record of pH measurements. Monitoring since 1998 has established a decline in pH that reflects the increase in atmospheric CO2 recorded at NIWA’s atmospheric research station near Wellington. The Munida time-series is led by NIWA’s Kim Currie, in collaboration with the University of Otago's Department of Chemistry. Every two months she has collected water samples along a 65-kilometre line from the tip of Otago Harbour out to sub-antarctic waters. This time-series is particularly valuable because it covers both subtropical and sub-antarctic waters in a one-day trip, so is in a unique location. During the transect University of Otago scientists measure the pH while Currie measures alkalinity, total dissolved inorganic carbon and CO2 as well as other related parameters. The supporting data help to determine what processes are causing changes in the properties of the water masses, including the changes in pH. For example, pH is linked to temperature and therefore varies between summer and winter and also year to year. Parameters in the data set include: XCO2_DRY - Mole fraction of carbon dioxide (dry air) in the headspace of the equilibrator, unit micromole / mole XH2O - Mole fraction of water vapour (dry air) in the headspace of the equilibrator, unit micromole / mole EQ_PRE - The pressure in the equilibrator head space in hectopascal EQ_TEMP - The temperature of the water in the equilibrator PCO2_WAT - The Partial pressure of carbon dioxide in the water body in units of microatmospheres
