The ocean waters surrounding New Zealand vary in temperature from north to south. They interact with heat and moisture in the atmosphere and affect our weather. Sea surface temperature changes with climate drivers such as El Niño, and will change with climate change. The sea surface temperature anomaly provides an indication of the heat change in the ocean.
Long-term changes and short-term variability in sea-surface temperatures can affect marine processes, habitats, and species. some species may find it hard to survive in changing environmental conditions.
The oceanic sea surface temperature data comes from the NIWA Sea surface temperature Archive (NSA). There are 2 datasets, of NSA Annual means and NSA Annual Anomolies, covering the Tasman, subtropical (STW) and Southern Antarctic (SAW) area and the total area. The data is available from 1993 to 2013 and the unit of measure is degrees celcius.

This dataset relates to the "Sea surface temperature" measure on the Environmental Indicators, Te taiao Aotearoa website.

Fine sediment is the collective term for inorganic particles smaller than 2mm that are deposited on the beds of rivers and streams. Urban development, agriculture, and plantation forestry around waterways can increase the amount of sediment entering river systems. Sediment can clog the spaces between pebbles used by aquatic insects and fish, and degrade food sources and sites used for egg laying. Excessive sedimentation can also affect the suitability of rivers and streams for recreation.

Predictions of the proportion of deposited fine sediment cover are provided for every river reach in the River Environment Classification. These were calculated via a regression model using the measured proportion of fine sediment cover, slope of the river, climate and catchment land cover.

NZREACH = River location ID from the River Environment Classification
pred_obs = predicted contemporary percent fine sediment cover
pred_expec = predicted pre-human percent fine sediment cover

This dataset relates to the "Stream bed sedimentation" measure on the Environmental Indicators, Te taiao Aotearoa website.

Freshwater fish are an important component of freshwater ecosystems and a valued resource for Māori and recreational fishers. The community of fish species found at a site can be affected by changes in catchment land cover and land use, in-stream habitat, fish passages (routes for moving up and down waterways), pests, and contaminants. The fish index of biotic integrity (IBI) is a measure of the condition of fish communities at sites across the country.

This dataset relates to the "Freshwater fish communities" measure on the Environmental Indicators, Te taiao Aotearoa website.

Fresh water in New Zealand is highly valued for recreational activities, including fishing. Freshwater angling (primarily for introduced ‘sports fish’ such as brown trout, rainbow trout, and chinook salmon) is a popular leisure activity. Fish licences issued by Fish & Game New Zealand provide an indication of recreational fishing activity at freshwater locations around the country.

This dataset relates to the "Participation in recreational fishing" measure on the Environmental Indicators, Te taiao Aotearoa website.

New Zealand’s indigenous and exotic forests absorb and store carbon from the atmosphere through photosynthesis. As forests grow, the carbon stored in them increases. These carbon stocks help offset greenhouse gas emissions from sources such as agriculture, energy production, and transport.

Column headings:
type = vegetation type of forest
vol_tC = volume of carbon in tonnes
