Entity Information

Entity Type Spreadsheet
Active Version? Y
Alias  
Schema Name  
» Description

Spreadsheet data including net-impact (A), and control site (C) information for substrate percent cover (bare, calcium carbonate algae, macroalgae, Porites compressa, sand, turf, sponge) and net area derived from the Structure from Motion imagery as well as net weight.
Change Summary

Null data cells or those populated with 'NA' represent data that was not collected.

In 2021, columns PC_TURF (percent cover of turf) and PC_MACRO (percent cover of macroalgae) were merged (summed) to create PC_ALGAE (percent cover of all algae). Also in 2021, the column PC_PCOM was renamed to PC_CORAL due to species other than Porites compressa being encountered, and represents the percent cover of all coral taxa present.

Data Attributes

Attribute Summary

Score Req'd? PKey? » Name Data Storage Type Description
100 No No DATE DATE Date of structure from motion survey (m/d/yyyy).
100 No No LAT NUMERIC Latitude in decimal degrees of structure from motion survey site.
100 No No LON NUMERIC Longitude in decimal degrees of structure from motion survey site.
100 No No DEPTH_MIN_M NUMERIC Minimum depth in meters of the 4 corners of the 3 x 3 m plot used to capture overlapping images processed using a Structure from Motion approach.
100 No No DEPTH_MAX_M NUMERIC Maximum depth in meters of the 4 corners of the 3 x 3 m plot used to capture overlapping images processed using a Structure from Motion approach.
100 No No DEPTH_AVG_M NUMERIC Average depth in meters of the 4 corners of the 3 x 3 m plot used to capture overlapping images to be processed using a Structure from Motion approach.
100 No No UniqID TEXT Unique identifier for survey site.
100 No No Site TEXT Site name.
100 No No Treatment TEXT Treatment type, A = net-impact site, C = control site.
100 No No Analysis_pair NUMERIC Number to associate each net-impact site with paired control site.
100 No No Net_area_m2 NUMERIC Area of net on substrate in square meters, calculated in GIS from the orthomosaic generated from the photographs. Not applicable to control sites (TREATMENT = 'C') and not collected in 2021 after net removal.
100 No No Net_wt_kg NUMERIC Weight of net in kilograms. Not applicable to control sites (TREATMENT = 'C') and not collected in 2021 after net removal.
100 No No Fouling_Code NUMERIC Fouling value assigned to each net. Fouling scores ranged from 1 to 3, where 1 = Light: 1–40% of net surface area covered, 2 = Moderate: 41–75% of net surface area covered, and 3 = Heavy: >75% of net surface area covered. Not applicable to control sites (TREATMENT = 'C') and not collected in 2021 after net removal.
100 No No PC_BARE NUMERIC Benthic cover category: bare substrate (0-100%). The sum of this and the other benthic categories totals 100%.
100 No No PC_CCA NUMERIC Benthic cover category: crustose coralline algae (0-100%). The sum of this and the other benthic categories totals 100%.
100 No No PC_SAND NUMERIC Benthic cover category: sand (0-100%). The sum of this and the other benthic categories totals 100%.
100 No No PC_SPONGE NUMERIC Benthic cover category: sponges (0-100%). The sum of this and the other benthic categories totals 100%.
100 No No PC_ALGAE NUMERIC Benthic cover category: all algae (turf and macroalgae combined) (0-100%).
100 No No PC_CORAL NUMERIC Benthic cover category: coral, all taxa (0-100%). The sum of this and the other benthic categories totals 100%. PC_PCOM changed to PC_CORAL in 2021 as other coral taxa besides Porites compressa were encountered.
