50417 Entity Published / External 25248 Baited Remote Underwater Video Station (BRUVS) Surveys of Fish in the Hawaiian Archipelago from 2012 to 2014 Data Set Data View BRUVS observation data Length_mm NUMERIC No No Active LENGTHS: Fork length of targeted fish for measurement in mm. Stage TEXT No No Active LENGTHS: Life cycle stage (AD = Adult; J = juvenile) Length_bin TEXT No No Active LENGTHS: Length category in 50-mm bins: <250, 250-300, 300-350, 350-400, etc. Fish less than 250 mm are binned into one category, and fish greater than 2000 m are binned into one category. Activity TEXT No No Active LENGTHS: Behavioral activity in the vicinity of BRUVS. Passing = transiting past the BRUVS bait bag. Attracted: approaching BRUVS bait bag, but not directly feeding. Feeding: directly feeding on bait in the bag, or consuming on particulates from the bait plume (emanating directly from the bait bag). Number NUMERIC No No Active LENGTHS: Default/only measurement is 1 (for single length measurement) 1 Region TEXT No No Active Pacific Islands Region where BRUVS surveys occurred. E.g. Main Hawaiian Islands = MHI, Northwestern Hawaiian Islands = NWHI. 2 Island TEXT No No Active Island or location within REGION where survey occurred 3 Method TEXT No No Active Default is "Baited" 4 Site TEXT No No Active BRUV deployment site, . Three-letter codes indicate ISLAND code (e.g. Oahu = OAH, Maui = MAI, French Frigate Shoals = FFS). Where deployments exceed 30-m depths, an additional "M" is added to the site label (e.g. OAHM, for an Oahu deployment exceeding 30-m depths). 5 Frame TEXT No No Active Video frame number where the MaxN estimate for any particular SPECIES was collected 6 Time_min TEXT No No Active Time (in minutes since the cameras were activated) where the MaxN estimate for any particular SPECIES was collected 7 Period TEXT No No Active Sampling duration of BRUVS (default is 0-60 minutes). Sampling period begins immediately upon BRUVS touchdown on the benthos (Time on Seabed). If TIME_MIN exceeds 60 min, PERIOD is NULL. 8 Period_time_min TEXT No No Active Time (in minutes since Time on Seabed) where the MaxN estimate for any particular SPECIES was collected. If TIME_MIN exceeds 60 min, PERIOD_TIME_MIN is NULL. 9 OpCode TEXT No No Active Concatenated descriptive code for each BRUV deployment, combining site, type of sampling (default is baited, B), number of deployments (default is 1), and duration (default period of 60 minutes). E.g. OAH602_B_1_60. 10 Tape_Reader TEXT No No Active Name or initials of video analyst 11 Depth NUMERIC No No Active Depth as recorded by BRUVS in meters 12 Depth_Type TEXT No No Active Indicates whether BRUVS surveys occurred in SPC depths (0-30 m) or mesophotic depths (>30 m) 13 Depth_Strata TEXT No No Active Indicates further stratification of sampling strata (SPC = 0-30 m; Upper mesophotic = 30-53 m; Lower mesophotic = 53-100 m) 14 Comment TEXT No No Active General comments regarding each individual deployment. TOFA = measurement was taken at the time of first arrival. 15 HabitatType TEXT No No Active Benthic habitats as described in Ayotte P., McCoy K., Heenan A., Williams I. & Zamzow J. (2015). Coral Reef Ecosystem Program Standard Operating Procedures: Data Collection for Rapid Ecological Assessment Fish Surveys. Pacific Islands Fisheries Science Center Administrative Report H-15-07, 33p. (e.g., aggregate reef, pavement, sand flat, spur & groove) 16 Substrate TEXT No No Active Benthic habitats from HABITATTYPE classified as either predominantly hard or predominantly soft (unconsolidated sediment) bottom. 17 Complexity TEXT No No Active Habitat complexity, ranked on a six point scale from low to very high (L=low; ML=medium low; M=medium; MH= medium high; H=high;VH=very high) 18 Complexity_No NUMERIC No No Active Habitat COMPLEXITY, converted from a text descriptor to numeric value from 1-6 (e.g. low complexity habitat = 1) 19 HardCoral NUMERIC No No Active Hard (scleractinian) coral cover (%) 20 SoftCoral NUMERIC No No Active Soft coral cover (%) 21 Macroalgae NUMERIC No No Active Macroalgae cover (%) 22 Turf NUMERIC No No Active Turf algae cover (%) 23 Sand NUMERIC No No Active Sand or unconsolidated cover (%) 24 CCA NUMERIC No No Active Crustose coralline algae cover (%) 25 Family TEXT No No Active Fish ID at family taxonomic level 26 Genus TEXT No No Active Fish ID at genus taxonomic level 27 Species TEXT No No Active Fish ID at species taxonomic level 28 Code TEXT No No Active Four letter code combining fish genus/species 29 Consumer_Group TEXT No No Active RELATIVE ABUNDANCE DATA: Identification of fish belonging to 1 of 4 consumer groups: Primary, Secondary, Planktivore, Piscivore 30 Trophic TEXT No No Active RELATIVE ABUNDANCE DATA: Consumer groups, subdivided into one of nine possible trophic groups 31 Endemic TEXT No No Active RELATIVE ABUNDANCE DATA: Specific to the Hawaiian Archipelago. Identifies whether a fish recorded by BRUVS is a Hawaiian endemic. 32 MaxN NUMERIC No No Active RELATIVE ABUNDANCE DATA: To avoid repeat counts of individual fish continuously re-entering a BRUVS field of view, the maximum number of individuals of the same species appearing at the same time (MaxN) is used as the relative abundance measure. 33 Has_Fed TEXT No No Active RELATIVE ABUNDANCE DATA: Identifies whether a species recorded by BRUVS has actively fed on the bait gov.noaa.nmfs.inport:50417 Annette DesRochers 2017-11-28T18:50:20 SysAdmin InPortAdmin 2022-08-09T17:11:37 2017-12-18 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No 2017-12-18 1 Year 2018-12-18
