This report provides an introduction to the 1995 NRA National Marine Baseline Survey. This survey consisted of four vessel campaigns in Winter, Spring, Summer and Autumn and two aircraft campaigns in Summer and Autumn. The four NRA coastal survey vessels were used to perform the boat work and a chartered light aircraft was used for the aerial surveillance work. The objective of this survey was to make measurements of background levels of contaminants to provide a baseline of water quality in the coastal zone. The Spring and Autumn campaigns were timed to coincide with the two main phytoplankton bloom events of the year, when Chlorophyll-a concentrations were likely to be at their highest. The summer campaigns provided a measure of the background levels of Chlorophyll-a since they were at a time when natural nutrient levels were expected to be low.
