Title:
Support for Macroalgal Ecology and Taxonomic Assessment for Coral Reef Assessment and Monitoring Program Sites, 2000-2002 for the Hawaiian Islands (NODC Accession 0000884)
Abstract:
The role that marine algae play in a coral reef system is often overlooked because of lack of knowledge that they are the primary producers in the system. The coral reef ecosystem in Hawaii contains about ten times more algal species than coral species, some of them regulating space that permits coral recruitment. This study took place during 2000-2002 at 44 sites for a total of 56 dives (each dive a unique day) on 7 of the major islands in Hawaii. Most sites correspond to the Coral Reef Assessment and Monitoring Program (CRAMP)locations, for which extensive monitioring of the coral and fish ecosystems have been undertaken from 1999-2002.

Why was the data set created?

(1) To understand better the role that marine algae play in a coral reef systems of Hawaii.(2) To generate an algal species list for each transect line, site and island (3) Collect voucher specimens of all species encountered including alien species, rare species new records and/or new species (4) To classify benthic habitat based on algal community structure (5) To estimate abundance and percent cover of various algal functional forms and species on transect lines.

    Date: Unknown (process 1 of 1)
    The Species List and Voucher Specimens - During the benthic surveys, the algal team member will swim transects and collect samples of as many macroalgal species aspossible. A 1 meter band on either side of the transect line will be surveyed and assessed. The first time that a diver encounters an alga on a transect line it will be collected and placed in a bag and as much collection information as possible will be noted. For all subsequent encounters the diver notes on his/her data sheet that the alga was seen again. Any and all rare or unknown species will be collected. If the divers have time at the end of a transect line they swim around and look for any other species that they may have missed. All samples collected in these surveys will be deposited as voucher specimens at the Bishop Museum's phycological collection. Quantitative Algal Assessment - As an integral component of the REA teams at least one algal diver will quantify and assess the benthic community. On each of the two 50 m transects that will be surveyed at each site five random points along each transect will be selected. At each of these locations, the point intercept method is used to estimate percent cover in 10 randomly placed quadrats along two 50 meter transect lines. These quadrat are 1/4 m2 in size and a total of 20 intersections areassessed per quadrat to quantify the benthic community. This data will be then be used to develop a quantitative algal database for the state of Hawaii and will be used in conjunction with other types of data (i.e. Fish Communities) to conduct multivariate community analyses.
