Summary

Abstract: The 2001 Environmental Sustainability Index (ESI) utilizes a refined methodology based on the 2000 Pilot ESI effort, to construct an index covering 122 countries that measures the overall progress towards environmental sustainability. The index is a composite measure of the current status of a nation's environmental systems, pressures on those systems, human vulnerability to environmental change, ...

Purpose: To provide a comparative index of national-level environmental sustainability based on lessons learned from the year 2000 pilot effort.

Quality Oceanography and nutrient measurements were taken where possible, which was not always at ideal locations. Therefore coverage of the area is not necessarily complete. Nutrient data were only recorded at 44 out of the 64 CTD stations. This cruise is however part of a series of 6 cruises which operated in this area, providing data from varying seasons and condition.

Data collection: A ... Neil Brown Mark III CTD (conductivity, temperature, depth probe #2941) system attached to a rosette water sampler (General Oceanics) was used for collecting continuous vertical profiles of conductivity and temperature. Water samples were collected at different depths using the rosette water sampler with 5L Niskin bottles. Measurements were made on the downcast, and water samples collected on the upcast. The water sampling depths were determined depending on the readings made during the downcast. The CTD was lowered at a rate as close to 1 m/sec, and raised between samples at speeds between 1 and 2 m/sec. Conductivity and temperature readings were also made at each water sampling station. 64 CTD stations were taken along a series of transects. Nutrient samples were taken at 44 of the CTD stations.

Ship-board processing: 250 mL water sub-samples were filtered through GF/F glass fibre filters, transferred to rinsed polyethylene bottles and immediately frozen. Water samples were analysed on board the ship for salinity and oxygen.

Post-ship processing: Oceanography data - Data was initially recorded on audio cassettes, but later replayed to produce digital nine-track magnetic tapes by a PDP 11/23. Data tapes were then processed on a VAX 11/750. For each CTD downcast, an uncalibrated, despiked file was generated, using a recursive filter to compensate for sensor mismatch. The data files were used to generate 2 dbar averages for in situ temperature, salinity, sigma-t, specific volumne anomaly and geopotential anomaly. The averages were centred on even, integral depths, and were only calculated when averages contained eight or more valid data points. The temperature and conductivity means were calculated for the interval, and the salinity calculated for the mid point of the pressure interval from the temperature and salinity means. Data processing software was supplied by CSIRO Division of Oceanography. Nutrient data - Analyses was completed by the Australian Government Analytical Laboratories for nitrate, nitrite, silicate, chlorophyll a and other pigments. Nitrite concentrations were found to be insignificant. The complete dataset is logically consistent, as krill and zooplankton hauls and phytoplankton pigment analysis were also obtained at the same sampling sites as the oceanographic and nutrient data. The cruise track was established before the experiment in order to eliminate bias. The oceanographic sampling was done as a supplement to the krill research program and the nutrient sampling to help interpret phytoplankton distribution and abundance, so sampling location and depth were not necessarily selected according to oceanographic or nutrient related considerations.
