New Zealand research tagging database

Study Extent

Species occurrence data collated from research tagging events in and around New Zealand waters.

Sampling

Biological data was sampled in-situ using a variety of equipment such as longlines, pots, rod and reels, and divers.

Quality Control

The scientific names have been mapped to the World Register of Marine Species (WoRMS), using the online taxon match tool. All sampling locations have been plotted on a map to perform a visual check. The most important check would be to see if all sampling locations are (1) in the marine and/or brackish environment and (2) within the described sampling area. There are some occurrences that appear to be on land. These are positions from commercial or recreational fishermen that are often adjusted to hide their true position for fear of giving away their real fishing grounds. These points are still included in this dataset as they do give an indication of the general area where the species occurrence was.

Method steps

1. Data was extracted from the tag database, then filtered for only records that have latitude and longitude values present.

Mainly around the New Zealand waters, but also around the South Pacific and Southern Oceans
