        abstract:  As part of the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS), the U.S. Fish and Wildlife Service conducted low-level (61m above sea level) seabird aerial surveys of Gulf of Mexico coastal waters out to 50nm offshore from the USA-Mexico border to Key West, FL (including the Dry Tortugas) from 2018-01-31 to 2020-02-12. Using a double-observer protocol, three observers collected data along 3 parallel 10nm transects spaced 1nm apart for 30nm transect/sampling hexagon units. Over 3 years, four survey events were completed representing greater than 36,000km of effort. Aerial survey crews recorded 13,581 avifauna detections representing 71,698 individuals. Observers identified 23 marine bird species (n = 52 all bird species identified) in total. Non-avifauna observations (e.g., marine mammals, sea turtles) totaled 3,160 individuals representing 2063 detections.
        purpose:  Improved information is needed on living marine resource abundance, distribution, habitat use, and behavior in the Gulf of Mexico to properly mitigate and monitor for potential impacts of human activities, including offshore energy development. Understanding of cumulative impacts on protected species in the Gulf of Mexico from both natural and anthropogenic forcing is required to inform NEPA assessments, consultations and rulemaking related to Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), and Migratory Bird Treaty Act (MBTA), as well as other statutes that govern bureau activities. The results of this study will provide important information to inform both Bureau of Ocean Energy Management (BOEM) and Bureau of Safety and Environmental Enforcement (BSEE) regulatory needs, as well as other agencies and stakeholders involved in effective management and conservation of protected species in the northern Gulf of Mexico. This dataset includes seabird visual observation data (with corresponding latitude and longitude locations), survey design spatial files (hexagons and transects), and the aerial survey Data Management Plan. This dataset also includes opportunistic non-seabird sightings such as marine mammals and sea turtles.

        supplementalInformation:  Despite the importance of the Gulf of Mexico for marine species, there is limited information available to quantify species-use in the region. To bridge this gap, the Gulf of Mexico Marine Assessment Program for Protected Species (GoMMAPPS), was developed as a federal partnership between the Bureau of Ocean Energy Management, the U.S. Fish and Wildlife Service, the U.S. Geological Survey, and the National Oceanic and Atmospheric Administration. Additionally, the seabird survey program worked in partnership with Michigan State University, Clemson University, and Terra Mar Applied Sciences LLC. For seabirds, a combination of ship-based and aerial surveys were employed (USFWS Quest Kodiak 100 Amphibious Aircraft). Low-level (61m above sea level) aerial surveys covering the coastal waters out to 50nm offshore were conducted from the USA-Mexico border to Key West, FL (including the Dry Tortugas) from February 2018 to February 2020. 180 40-km2 hexagonal survey units from the U.S. Environmental Protection Agency’s Environmental Monitoring and Assessment Program (US EPA EMAP; White 1992) were randomly selected by generalized random tessellation stratified sampling (GRTS). For each hexagon, a random flight direction was selected, thus defining two additional, adjacent hexagons and creating a three-hexagon sampling unit. Using a double-observer protocol, three observers collected data along 3 parallel 10nm transects spaced 1nm apart for 30nm of transects/sample unit. Observers surveyed the same sampling units (or a subset of these due to weather constraints) in each survey event (a survey event is a single survey season, e.g., winter 2018). Over 3 years (2018-2020) four survey events were completed; 600 hexagons were surveyed in total representing 1,800 transect segments and >36,000km of effort. Aerial survey crews recorded 13,581 avifauna detections representing 71,698 individuals. Observers identified 23 marine bird species (n = 52 all bird species identified) in total. Non-avifauna observations (e.g., marine mammals, sea turtles) totaled 3,160 individuals representing 2063 detections. Submission Package ID: ARYMDB

                description:  Parameter or Variable: SPECIES IDENTIFICATION - COUNT (measured); Units: n/a; Observation Category: in situ; Sampling Instrument: biota surveys; Sampling and Analyzing Method: Using the U.S. EPA Environmental Monitoring & Assessment Program’s 40-square kilometer hexagon sampling grid (White 1992) and a generalized random tessellation stratified sampling technique, a random sample of 180 hexagons were selected to survey. Flight direction for each hexagon was also randomly selected, and included two additional, adjacent hexagons. Across each group of three hexagons, three parallel transects were established as the sampling unit. Two aircrafts (US Fish & Wildlife Service Quest Kodiak 100 Amphibious Aircrafts) were used to conduct aerial transect surveys from Brownsville, TX to Key West, FL out to 50 nautical miles from the shoreline. All surveys were conducted at an altitude of 61m and flown at approximately 110 knots. The surveys consisted of a double observer protocol with three observers collecting data in each aircraft: the pilot-biologist and two biologists who rotated their seat position daily. In-flight observers recorded all detections (species identification to the lowest taxonomic level and number of individuals counted) from the observable portion of the plane up to 200m out, on either side of the aircraft, for a 400m strip transect. Seabird species observed:; Data Quality Method: Observations and location information were collected simultaneously using onboard laptops installed with the Hodges RECORD program (Hodges, unpublished software) and the survey system installed in each aircraft to obtain GPS information. Each day, each observer downloaded two ASCII files from the on-board computers to a thumb drive. If the non-pilot observers rotated seats midday, they would download two files from each computer/seat they made observations from on that day. Using the Hodges TRANSCRIBE program (Hodges, unpublished software), observers then transcribed their recorded data nightly into two .txt files: observations and track. The Hodges TRANSCRIBE program automatically formatted the observation data, inputting the corresponding header information (e.g., observation date, survey hexagon and transect, latitude, longitude, species, count, etc.). The track file recorded the flight path of the plane. Observers then sent the two (or four if they rotated seats) .txt files (observations and tracks) to the GoMMAPPS seabird Data Specialist. Data files were checked for errors, imported into R Studio (R Core Team 2020), and QA/QC'd. Clean data were combined into one single .csv file for all aerial surveys within the study period and prepared for archive..
