Title:
Investigation of the marine communities of Midway Harbor and adjacent lagoon, Midway Atoll, Northwest Hawaiian Islands in 1998 (NODC Accession 0001098)
Abstract:
A survey of the marine communities of Midway Atoll harbor and surrounding lagoon was conducted at 12 sites from September 5 to 9, 1998. The primary focus of these surveys was the invertebrates of the fouling communities present on artificial substrates. Occurrence of reef fishes at each site was also recorded, and algae was collected and identified from four stations. A total of 444 taxa were identified (47 algae, 316 invertebrates, and 81 fishes) from all stations. Approximately 250 invertebrate and 35 algae species are considered new records for Midway Atoll. All fishes observed were previously recorded from the atoll. Only three invertebrates identified in this survey are considered to be nonindigenous species in the Hawaiian Islands. One introduced bryozoan, Amathia distans, dominated the fouling communities at most stations where artificial substrates were available. Another introduced bryozoan, Schizoporella errata, was also common at the same stations. A non indigenous barnacle, Chthamalus proteus, recently introduced from the Caribbean, was common on pier pilings inside Midway harbor. No introduced invertebrates were present in natural habitats. The introduced snapper, Lutjanus kasmira, was also present along the reef outside the lagoon. The threat to the native reef community by established non-indigenous species is considered minimal. The presence of these introduced species at Midway, especially Chthamalus proteus, suggests that vectors of future, potentially more deleterious introductions exist. Transport of these introductions was most likely as fouling on ship bottoms, but other sources of introductions, such as ballast water carried in ships, should be guarded against to protect the relatively pristine reefs of Midway Atoll.

  2. How were the data generated, processed, and modified?
    Date: Unknown (process 1 of 1)
    Sampling was conducted at 12 stations around and within the atoll. Benthic organisms were collected from a variety of substrata using standard collecting techniques while using snorkel or SCUBA. Sampling locations were chosen to assure that a wide range of environmental conditions were assessed. The primary focus was placed upon fouling organisms which adhere to hard artificial surfaces such as cement dock pilings, but other natural substrates were investigated as well. The infaunal and epibenthic fauna of the sediments at some stations were also sampled using a hand held coring device. Visual observations of large benthic invertebrates and fishes were also recorded at each station. Organisms collected were preserved in 70% EtOH and returned to the Bishop Museum laboratory where they were sorted and identified to the lowest taxonomic level possible. Some individuals will be sent to specialists for verification of the identifications reported here. Given the difficulty of identifying some organisms and the instability of taxonomy in general, several of the species names in this report will undoubtedly need revision.
