    The biological data from the IPY-CAML voyage (TAN0802) by the R/V Tangaroa is available as an Darwin Core archive through the Southwestern Pacific OBIS IPT node. The TAN0802 voyage departed from Wellington, New Zealand, on 26 Jan 2008 and returned to Wellington, New Zealand, on 21 Mar 2008. The survey was concentrated mainly in the Ross Sea and the waters around Scott Island and the Balleny Islands. Biological data were collected using a variety of gear, including: bottom trawls, beam trawls, epibenthic sleds, van Veen grabs, rosette water bottles and MOCNESS tows.

    The High risk site surveillance programme for non-indigenous marine species, delivered by NIWA under contract to Ministry of Primary Industries (MPI), is designed to detect the presence of a group of non-indigenous or potentially invasive marine animals and plants that MPI have identified as presenting a significant risk of arriving and establishing in New Zealand. A variety of techniques designed to sample a range of habitat types encompassing soft and hard surface habitats such as mud and gravel bottoms, intertidal rocky shores, and artificial structures, including marina pontoons, pilings, moorings, jetties and commercial vessel berths were used. The sampling techniques include crab condo lines, crab box traps, starfish traps, epibenthic sled tows, and diver and shore searches. These surveys have been undertaken biannually since 2002 in up to 11 ports and harbours in New Zealand.

    Comprehensive marine biological baseline survey data from 24 ports and marinas around New Zealand. Sampling techniques included: videography, diver observations, destructive quadrat sampling, benthic grabs and sleds, 4 different types of baited trap, and sediment cores were taken to sample the resting cysts of dinoflagellates. Also included are the baseline survey data for four ports completed by Golder in 2006/2007 at the Chatham Islands, Stewart Island, Manukau Harbour and Golden Bay.
