Biodiversity
1. Review what is already known of abyssal, canyon and trench faunas in NZ.
2. Review what is already known of abyssal, canyon and trench faunas around
the world.
3. Prioritise science questions and locations for exploration.
4. Assess NZ capacity to sample at the required depths; identify sampling
equipment needs.
5. Design a suitable vessel-based sampling programme
1. To improve understanding of the effects of trawl fishing in New Zealand on the
biodiversity of seamounts- knolls and hills.
2. To describe differences in benthic biodiversity between northwestern and
eastern regions of the Chatham Rise
3. To continue the time series of observations in the NW Chatham Rise to
demonstrate recovery in terms of biodiversity
4. To extend the observations on fished-unfished contrasts and recovery of
fauna on protected seamounts to an oceanographically distinct location
1. To measure and describe key elements of species distribution- abundance
(density or biomass) & biodiversity for the Ross Sea and Southern Ocean for
main habitats and key functional ecosystem roles- for major groups- virusesbacteria-
archaea........
2. To report on the diversity of Antarctic Cephalopoda (Octopus and Squid)including
a complete inventory of taxa- & reports on ontogenetic & sexual
variation in species- their systematics- diversity- distribution- life histories- &
trophic importance.
3. To Beak/Biomass Regression Equations
4. Life cycle determination
