Natural Geography In Shore Areas (NaGISA) Dataset Version 1, Released 2005.Entry ID: nagisa1
Abstract: This dataset provides data collected during the Natural Geography In Shore Areas (NaGISA) quantitative global nearshore census. The data is coming in (i.e. the dataset is continually being added to and should not be considered complete) from a growing set of globally distributed standard transects from the high inter-tidal zone to the depth of 20m, most of which will be repeated, and many of which ... are being uploading in stages (i.e. taxonomic detail will improve with time). Target habitats are globally distributed algal and hard-bottom and sea-grass and soft-bottom communities. For each study site, replicate samples are collected at high, mid and low inter-tidal and 1, 5 and 10m sub-tidal depth (where possible at 15 and 20m).
The NaGISA protocols (which are standardized) include:
(1) Passive sampling, photography and observational techniques, estimates of percent cover of colonial invertebrates and rhizoidal macro algae and counts of algal stripes and solitary fauna within quadrates. (2) Active sampling, core samples of sea grass beds, and careful removal of organisms from small quadrats within macro algal sites.
(3) Assessment, measurements of surface and bottom seawater temperature and a visual classification of substrata.

Quality Data was collected on rocky shores from high tide to 20m depth: direct observation of species within replicate 1m2 quadrats, and collection of all species within replicate 50cm2 and 25cm2 quadrats. In the centre of sea grass beds: (a) direct observation of species within replicate 50cm2 quadrats, and collection of all species (b) >0.5cm in size within replicate 15cm radius by 10cm depth cores, and (c) between 0.5cm-63um in size within replicate 2cm radius by 10cm depth cores. See http://www.nagisa.coml.org/Protocols for more details.
