Data Attribute / Type Description
DATE
DATE 		Date of structure from motion survey (m/d/yyyy).
LAT
NUMERIC 		Latitude in decimal degrees of structure from motion survey site.
LON
NUMERIC 		Longitude in decimal degrees of structure from motion survey site.
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.
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.
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.
UniqID
TEXT 		Unique identifier for survey site.
Site
TEXT 		Site name.
Treatment
TEXT 		Treatment type, A = net-impact site, C = control site.
Analysis_pair
NUMERIC 		Number to associate each net-impact site with paired control site.
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.
Net_wt_kg
NUMERIC 		Weight of net in kilograms. Not applicable to control sites (TREATMENT = 'C') and not collected in 2021 after net removal.
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.
PC_BARE
NUMERIC 		Benthic cover category: bare substrate (0-100%). The sum of this and the other benthic categories totals 100%.
PC_CCA
NUMERIC 		Benthic cover category: crustose coralline algae (0-100%). The sum of this and the other benthic categories totals 100%.
PC_SAND
NUMERIC 		Benthic cover category: sand (0-100%). The sum of this and the other benthic categories totals 100%.
PC_SPONGE
NUMERIC 		Benthic cover category: sponges (0-100%). The sum of this and the other benthic categories totals 100%.
PC_ALGAE
NUMERIC 		Benthic cover category: all algae (turf and macroalgae combined) (0-100%).
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.

Entity Information

Entity Type: Spreadsheet
Active Version?: Yes
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.
