Description

Forty-five species of marine benthic macroalgae were identified from the coral reefs of Rose Atoll, American Samoa (Rose Atoll Marine National Monument). The algal collections were made during the February 2002, February 2004, March 2006, and March 2008 Pacific Reef Assessment and Monitoring Program (Pacific RAMP) under the auspices of the U.S. National Oceanic & Atmospheric Administration (NOAA), Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Division (CRED). The collections included 6 species of Cyanobacteria, 14 species of red algae, 4 species of brown algae, and 21 species of green algae. Nine species represented new records for the Samoan Archipelago (American Samoa and Samoa). Based on their occurrences, eight species of green algae were considered most broadly distributed among the stations during all four expedition years. The top three broadly distributed species were Halimeda taenicola, Halimeda micronesica, and Caulerpa cupressoides.

Data Records

Sampling Methods

Rose Atoll was visited as part of the U.S. National Oceanic and Atmospheric Administration’s (NOAA) Pacific Islands Fisheries Science Center’s (PIFSC) Coral Reef Ecosystem Division’s (CRED) Pacific Reef Assessment and Monitoring Program (Pacific RAMP). Stations at Rose Atoll were identified using the first three letters of the island’s name, e.g., ROS-05P-04 signifies Rose Atoll (ROS), permanent station number (05P), and the year 2004 (04) when the specimens were collected. The designation “b” after a station number refers to a site visited only by the benthic team.

Study Extent Swains Island, American Samoa

Method step description:

  1. Algal samples were hand collected by scuba divers following the protocol of Preskitt et al. (2004) where transects were mainly at depths of 12.2 to 18.3 m; and immediately frozen. Algae were collected at one shallow station (ROS-24-04) at 1.2 m deep and one deeper station (ROS-16-02) at 27.4 m. Prior to taxonomic examination, plastic bags of frozen algae from each station were thawed in tap water. Thawed seawater was poured carefully from the bag and replaced with 4% formalin in seawater to prevent the fragile turf algae and epiphytes from decomposing. The collections were examined using a dissecting microscope, and representative epiphytes and turf were separated. The small specimens were mounted on glass slides by decalcifying with 10% hydrochloric acid, staining with aniline blue, and mounting with 30% corn syrup (Karo) with phenol. Larger specimens were mounted on segments of herbarium paper. A maximum of five specimens served as vouchers for each species recorded here.
