Summary
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.
Entity Information
Entity Type
Spreadsheet
| 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

| 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. |
