title: Mangroves monitoring - Snappers. In dataMares: Ecological Monitoring

description: These surveys are conducted by researchers who snorkel along a 50 m transect along the perimeter of the mangrove, identifying, size-estimating, and counting each fish observered within a 1 m swath on each side of the transect. The numbers of individuals in each species and size category are recorded. This dataset includes data from 2006 to 2009 on fishes of the family Lutjanidae (snappers), an important group for fisheries and one which depends on the mangrove fringe as nursery habitat, and combines them with descriptions of the geological substrate, location, and extent of the mangrove forest at each site.

description: The Gulf of California Marine Program and El Centro para la Biodiversidad Marina y Conservacion have collaborated in a long-term monitoring effort of marine habitats in the Gulf of California since 1998. These data allow researchers to assess changes in habitat and wildlife populations over time. Mangroves, one of the habitats in the Gulf included in the monitoring program, are surveyed for the populations of fish living in the fringe of prop roots of Rhizophora mangle (red mangroves) at the waters edge of mangrove forests. These surveys are conducted by researchers who snorkel along a 50 m transect along the perimeter of the mangrove, identifying, size-estimating, and counting each fish observered within a 1 m swath on each side of the transect. The numbers of individuals in each species and size category are recorded. This dataset includes data from 2006 to 2009 on fishes of the family Lutjanidae (snappers), an important group for fisheries and one which depends on the mangrove fringe as nursery habitat, and combines them with descriptions of the geological substrate, location, and extent of the mangrove forest at each site. In 2007 and 2009, the two years with the most comprehensive sampling of mangrove sites, the data show that the densities of juvenile snapper at each site--and thus the productivity of each mangrove in terms of recruitment to local fisheries--changes from year to year. In 2007, rocky mangrove habitats throughout the region produced more juvenile snappers than sandy habitats, while in 2009, all habitats in the central Gulf were consistently more productive than all those in the sourthern Gulf. These results highlight the productivity of mangrove habitats to offshore fish populations and fisheries and demonstrate the significant effects of interannual environmental variation (e.g., El Nino/Southern Oscillation) on the nursery function of these habitats.

title: Assessing the role of fish in kelp forests and rocky reefs. In dataMares: Ecological Monitoring

description: The sampling consisted of underwater visual censuses performed by scuba divers carrying out belt transects of 30 meters length (verified with tape measure) and a window of 2x2 meters of amplitude (30 × 2 m, assessment unit: 60 m2). For each locality, 6 transects were done. In the case of the kelp forest ecosystem, three transects were done in the benthic zone, and three in the midwater zone. The midwater position was weighted by the depth of the sampling site; 4-6 m from the bottom if the depth in the site is less than 10 m and 6-8 m if the depth is greater than 10 m. In the case of Rocky reef ecosystem all transects were done in the benthic zone. Transects were made trying to keep the same direction and speed, and changing direction between transects to avoid pseudoreplicate. To record the species and their sizes, acrylic boards and plastic paper (Duracopy) were used. All transects were performed between 08:00 a.m. to 2:00 p.m.

title: Point Intercept Transect method in the ecological monitoring of the Rocky Reefs in the Gulf of California. In dataMares: Ecological Monitoring

description: This database is the result of the Point Intercept Transect method, where using transects at 20 and 5 meters in depth with 5 replicates, the type of cover is counted (macroalgae, sessile invertebrates, sand, etc.) every 20 cm for a total of 10 m. The count of each kind of substrate is converted to % of cover by the sum of the total counts of a site depth, and dividing it for the total points (250) and finally multipling the results by 100. The goal of the project is to investigate the structure of benthic macroalgae and invertebrates in the Gulf of California, Thanks to the cover data of macroalge a first baseline available for the rocky reefs is generated for these taxa in the Gulf. Data were collected over three years 2016, 2017 and 2018.

title: Labeled mangrove sites of Baja California Sur. In dataMares: Ecosystem Dynamics

description: Shape file. Coordinate system: WGS 1984.
description: This database consists of 14 sites of mangroves from Puerto San Carlos and La Paz, Baja California Sur, from 2018 and 2019. These sites were imaged using a Phantom 4 Pro at 120 meters altitude, resulting in a 3 cm per pixel resolution. Mangrove and nonmangrove labels were labeled using QGIS. The imagery collection and labeling process was led by Astrid Hsu, Eric Lo, Beni Guerrero, and John Dorian.
description: Images were collected using a drones flying over mangroves at 120 meters in altitude. The full protocol can be viewed at https://escholarship.org/uc/item/2zv0z6zm. Orthomosaics were then created using Agisoft Metashape. Orthomosaics were exported as tif files and uploaded to QGIS 2.4 or newer. Using this platform, labelers drew geo-referenced polygons and classified areas as mangrove or nonmangrove.
