Temporal coverage: first record 1992 (ongoing) Number of sites: 9 sites (3 in each of three zones - dumping area, spreading zone, control zone) Sampling frequency: Once in the second year after consent (1995) and thereafter at 3-yearly intervals. In 2007 this changed to 5-yearly intervals. Main marine environment sampled: Marine Depth zone: Subtidal Sedimentary type: Soft Community association: Mud Sampling method: Sediment cores, infauna cores, shellfish collection Parameters collected: Sediment contamination, infauna community composition, shellfish tissue contamination Measured variables: Infaunal community composition, sediment metals (Cu. Pb, ZN), sediment grain size, shellfish tissue (Austrofusus glans) contamination (organochlorine pesticides, PCBs, Hg), shellfish imposex assays Species/community data: Benthic infauna Other data collection: There was a baseline/preliminary survey carried out by the Cawthron Institute in 1992 (Roberts 1992) Ongoing as part of their consent Quality assurance: Yes Port Nelson Ltd AND Cawthron Institute Ross Sneddon Cawthron Institute +64 3 548 2319 +64 3 546 9464 98 Halifax Street East Nelson 7010 New Zealand ross.sneddon@cawthron.org.nz http://www.cawthron.org.nz/ WWW:LINK-1.0-http--link Link to the website of the Cawthron Institute marine benthic soft ecological chemistry physical core MEMP No known constraints. eng environment Tasman Bay 173.000 173.419 -41.135 -40.789 https://dc.niwa.co.nz/niwa_dc/srv/metadata/48e6a4a3-a8f3-4c75-ba62-19a6d8370cf8 WWW:LINK-1.0-http--metadata-URL Point of truth URL of this metadata record
