Surveys for adult invertebrates that were part of the hull fouling communities were done to determine to what extent marine alien invasive species (AIS) are being transported in this fashion. The focus was to perform a qualitative analysis that created a species inventory. The organisms that generally foul vessel hulls are the typical species found in natural marine intertidal and subtidal fouling communities. These organisms are usually associated with one of the following groups: porifera (sponges), coelenterata (hydroids, corals and anemones), mollusca (mussels, clams, and sea slugs), annelida (marine worms), arthropoda (barnacles, amphipods, and crabs), bryozoa (moss animals), chordata (sea squirts and fish), as well as macroalgae (seaweed). Through collaboration with state and private industry representatives, arrivals notification for various vessel types was received. This arrivals information was used to schedule field survey activities throughout the study. Field work occurred in 2003 at harbors of southern and southwestern coasts of Oahu, Hawaii.
Better understand hull fouling as a mechanism for the introduction and dispersal of marine alien species in the main Hawaiian Islands.

Sampling: Port Arrivals 1) Identify vessel for survey A) Commercial vessel - consult vessel arrival schedules maintained by State of Hawaii Department of Transportation, Harbors Division B) Personal Craft - consult with harbor master of public or privately owned marinas to provide arrivals information. Public marinas: State of Hawaii Department of Land and Natural Resources, Division of Boating and Ocean Resources. Private marinas: consult marinas listing in Hawaii Ocean Industry and Shipping News publication 2) Contact vessel owner/operator to obtain particulars (ie. Last port, vessel maintenance records...) and permission to conduct hull survey A) Commercial vessel - either directly or through the shipping agent B) Personal Craft - speak directly to owner/operator 3) Survey entire hull from bow to stern on port and starboard sides with SCUBA and collect a representative sample of all taxonomic groups present. 4) Record the overall percent cover of fouling in each of the following sections of the vessel: A) Bow B) Midship C) Stern D) Prop and rudder E) Above the water line Compilation of arrival patterns and vessel operation dynamics 1. Introduction: The objective of this aspect of the field component was to create a profile for the last port of call for specific overseas arrivals. The specific vessels for which information was gathered were overseas cargo barges, foreign fishing boats and overseas personal craft. 2. Methodology: There were three separate data sources for these vessel types. The overseas cargo barges and foreign fishing boat arrivals information was obtained through the State of Hawaii Department of Transportation, Harbors Division. Overseas personal craft arrivals had to be further divided into those arriving from domestic ports and those arriving from foreign ports. Data for domestic port arrivals exists with the State of Hawaii Department of Agriculture, Plant and Animal Quarantine and Inspection Division. The U.S. Customs Service collects information on the arrival of overseas personal craft from foreign ports. The information for both agencies existed in hand-written logs, and permission was secured to allow access. The logs from May 2001 through June 2003 for both types of arrivals were entered into a spreadsheet format for analysis. The arrivals information for a two year period of time was analyzed for all the target vessel types. The overseas barges and foreign fishing boat arrivals data was from a data set obtained for the two year period of time from January 1997 through December 1998. This data set was from the daily arrivals logs for Honolulu Harbor and Kalaeloa Barber's Point Harbor for this period and was entered prior to this project. An analysis of recent data revealed that the arrivals data for this period was still characteristic of both harbors, so this data set was used instead of re-entering a new set. The data for overseas arrivals of personal craft was separated by domestic and foreign arrivals for the purpose of presentation and analysis of temporal trends. A temporal trend analysis was not done for the overseas barges or foreign fishing boats since they are on more regular commercial schedules. Last port of call information for the overseas barges and foreign fishing boats was non-specific in some case so the presentation scheme to categorize this information was the United Nations Food and Agriculture Organization (FAO) ocean regions. All but a few of the records of personal craft included specifics on last port of call, which allowed more specific data to be presented on last port of call. Finally, a brief narrative of the spectrum of the operational dynamics of each vessel type was developed. This narrative will examine the activities of each vessel type to qualitatively determine if there are additional concerns that relate the marine AIS.
Data files placed in three directories: access/, doc/, excel/ 1) Directory: access/The original file received was Vessel_Data.mdb. Tables were saved in MS Excel (1997-2000) format, which inturn were saved as Comma Separated Versions (CSV) ASCII files.The tables are: Sample_Location, Sample_Method, Vessel_Data, andVessel_Type. The contents are self explanatory.2) Directory: doc/The original file received was NODC_Narrative.doc, which wasexported into an ASCII text file of the same name. It containsinformation about the dataset.3) Directory: excel/The original file received was National_Oceanic_Data_Center_File.xls.It contained two sheets, which were saved as Comma Separated Versions (CSV) ASCII files: field_data.csv and formal_species_list.csv. Theseare the inventory and analysis files.
