Assessment of species composition, diversity, and biomass in marine habitats and subhabitats around offshore islets in the main Hawaiian islands, 2007, April 2 - September 20, 2007 (NODC Accession 0042684)

The marine algae, invertebrate and fish communities were surveyed at ten islet or offshore island sites in the Main Hawaiian Islands in the vicinity of Lanai, (Puu Pehe and Poo Poo Islets), Maui (Kaemi and Hulu Islets and the outer rim of Molokini), off Kaulapapa National Historic Park on Molokai (Mokapu, Okala and Namoku Islets) and Oahu (Kaohikaipu Islet and outside Kapapa Island) in 2007. Survey protocol at all sites consisted of an initial reconnaissance survey on which all algae, invertebrates and fishes that could be identified on site were listed and or photographed and collections of algae and invertebrates were collected for later laboratory identification. Following the reconnaissance surveys, quantitative estimates of coral and algal coverage and size and biomass of fishes along 25 m transects were conducted at each site and their locations were recorded using GPS.

The original data are primarily provided as MS Excel spreadsheets with associated reports as .doc and .pdf files. Supplementary data is provided as .dbf files to use in a GIS. Associated data, primarily .jpg image data files, are filed under NODC Accession Number 0043046.

2007年，研究人员于夏威夷主群岛拉奈岛周边（普佩赫岛与波波岛）、毛伊岛周边（凯埃米岛、胡卢岛及莫洛基尼火山口外缘）、莫洛凯岛考拉帕帕国家历史公园海域（莫卡普岛、奥卡拉岛与纳莫库岛）以及瓦胡岛（卡奥希卡伊普岛与卡帕帕岛外侧）的10个小岛或离岸岛点位，开展了海藻、无脊椎动物与鱼类群落调查。所有调查点位均采用统一流程：首先开展初步踏勘，对现场可识别的海藻、无脊椎动物及鱼类进行名录登记或拍摄存档，并采集海藻与无脊椎动物样本用于后续实验室鉴定。踏勘完成后，在各点位沿25米样带开展珊瑚与海藻覆盖度、鱼类体长及生物量的定量估算，并通过全球定位系统（Global Positioning System，GPS）记录各点位坐标。
