<br /><strong>Updated with new data on 02 Dec 2023</strong><br />
<p>This data set measures the rise in annual mean sea level relative to land referenced to the latest Intergovernmental Panel on Climate Change (IPCC) 1995 to 2014 baseline period mean sea level at four longer-term sites between 1901 and 2020:<br>
• Auckland<br>
• Wellington<br>
• Lyttelton<br>
• Dunedin<br>
and two additional sites with shorter time series:<br>
• Moturiki, Mount Maunganui (1951 to 2020)<br>
• New Plymouth (1920 to 2020).<br>
Relative sea-level rise includes the vertical land movement of the surrounding area (for example, a sinking landmass increases the relative rise in sea level).</p>
<p>We report on linear trends for sea-level rise for the full period between 1901 and 2020 for the four longer-term sites. We also publish the linear trends for these sites for two time periods: 1901 to 1960 and 1961 to 2020. For Moturiki and New Plymouth, we publish linear trends for the 1961 to 2020 period only.</p>
<p>Variables:<br>
site: The location of the tide gauge used to measure coastal sea level. Site refers to the name of nearest settlement. This dataset provides sea-level data for: (i) Auckland - Port of Auckland, Waitemata Harbour; (ii) Moturiki - Moturiki Island (Mount Maunganui); (iii) New Plymouth - Port Taranaki (New Plymouth); (iv) Wellington - Lambton Harbour (Wellington); (v) Lyttelton - Lyttelton inner harbour, and; (vi) Dunedin - Dunedin harbour basin (Otago Harbour)."<br>
trend_start_year: The first year in the annual mean sea level time series that the trend relates to.<br>
trend_end_year: The last year in the annual mean sea level time series that the trend relates to.</p>
<p>msl_trend: The estimated annual change in coastal sea level based on the trend assessment (in other words, the slope of the linear trend line). Trends were calculated using weighted linear regression models. The models used annual mean sea level data (relative the baseline) that was weighted to account for years that had less than 12 monthly average mean sea level values. Models also accounted for climatic conditions of temperature and pressure. Refer to the technical report that NIWA supplied alongside the data for more information <a href="https://environment.govt.nz/publications/update-to-2020-of-the-annual-mean-sea-level-series-and-trends-around-new-zealand/">environment.govt.nz/publications/update-to-2020-of...</a><br>
standard_deviation: The standard deviations of the estimated annual mean sea level values based on the trend assessment.<br>
units: The units of the estimated annual mean sea level values based on the trend assessment.<br>

<p>These data estimate the occurence of extreme wave events in coastal and oceanic waters for 2012, particularly for wave events where significant wave height exceeds a threshold of 8 metres and for a period of at least 12 hours. Significant wave height is defined as four times the square root of the variance of sea surface elevation due to wave motion.</p>

<p>The 15 class Benthic-Optimised Marine Environment Classification (BOMEC). The BOMEC divides the benthic environment into ecosystem types. These are grouped into three inshore groups, three continental shelf groups, and nine deeper-water groups. Each group represents areas with similar environmental variables, such as depth, temperature, salinity, and suspended sediment. The classification system considers the distributions of eight benthic taxonomic groups: asteroids, bryozoans, benthic foraminiferans, octocorals, polychaetes, matrix-forming scleratinian corals, sponges, and benthic fish.</p>

<p>Extreme wave indexes estimate the occurrence of extreme wave events in coastal and oceanic waters. Extreme wave indexes estimate the number of times a significant wave height exceeds one of three threshold values for at least 12 hours in 24 marine regions. The three wave-height thresholds are four metres, six metres, and eight metres.<br>
This indicator estimates the exceedances of a wave-height threshold for each year from 2008 to 2015 in coastal regions.<br>
Significant wave height is a measure of the ‘typical’ wave height in a place over a time period. It is four times the standard deviation of the water surface if, for example, you were to measure water moving up and down a jetty piling for an hour. The largest individual wave will typically have a height around twice the significant wave height.<br>
We use three wave-height thresholds because of the regional variation in extreme wave events. In general, the north experiences less exposure to consistently strong winds, and the waves generated by them, than the south. Four-metre tall waves are considered extreme in the northern-most parts of New Zealand but are more common in the south. For the southern-most parts of New Zealand, eight-metre waves better represent extreme wave events.<br>
This dataset relates to the number of extreme wave events exceeding the four metre threshold in coastal regions.</p>

<p>The ocean storm index estimates the number of days in a year when wind speeds exceed gale and storm force on the Beaufort Scale. In a gale, sea conditions are rough and waves can be over six metres high. In a storm, waves can be over 10 metres high. To put this into context, on land a near gale would make walking difficult, and a storm would cause some damage to roofs, chimneys, and trees. Climate change could lead to changes in the frequency and intensity of storms. More frequent and intense storms will likely be a stressor for habitats and species.<br>
The ocean storm index estimates the number of days that wind speeds exceed gale and storm force on the Beaufort Scale. The Beaufort Scale is a widely used international classification that rates sea conditions from 0 (calm) to 12 (hurricane). We report on estimated wind speeds broken down to:<br>
- gales – measure 8 on the scale, have rough sea conditions with wind speeds of approximately 62–74 km per hour and wave heights of 5.5 metres<br>
- storms – measure 10 on the scale, have wind speeds of approximately 89–102 km per hour and wave heights of 9–11.5 metres (McDonald & Parsons, 2016).<br>
This dataset relates to the average number of days wind speed exceeded storm force (Beaufort Scale 10) from 1979–2015.</p>

<p>The average concentration of chlorophyll-a (chl-a) in phytoplankton for 2015.<br>
Concentrations of chl-a in phytoplankton are used to assess primary productivity in our oceans. Phytoplankton are primary producers of biomass (mass of living organisms) and form the main basis of marine food chains. They use the chl-a pigment to capture the sun’s energy through the process of photosynthesis. Phytoplankton growth is affected by the availability of nutrients and light, which in turn are affected by the structure of the surface water column. The surface water column structure is affected by oceanographic and climate processes; large-scale changes to climate and oceanographic conditions can lead to changes in phytoplankton growth and chl-a concentrations.</p>

<p>New Zealand’s four million km2 marine environment is diverse, with a range of coastal habitats and offshore seabed environments. There are also many marine species unique to New Zealand. Marine protected areas conserve or manage some of these unique habitats and species, while a range of other tools also provide marine protection. We report on the area covered by these tools as an indirect measure to understand the state of the marine environment.<br>
Benthic protection areas (protected seabed areas) are one of the marine protection tools used. They are designated areas in the exclusive economic zone, which extends from the 12 nautical mile seaward limit of the territorial sea to the 200 nautical mile limit. Bethnic protection areas protect seabed habitats through the prohibition of bottom trawling and dredging. There are some areas where seamount closures overlap with benthic protection areas. In these cases the seamount closure restrictions apply.<br>

Marine mammal sanctuaries are one of the marine protection tools used. They are designed to protect New Zealand’s unique range of marine mammals by reducing harmful human impacts, particularly in vulnerable areas such as migratory routes and breeding grounds. Each marine mammal sanctuary has a specific set of restrictions based on the species that occupy, or pass through that particular area.</p>
