26865 Linkages Data Set Published / External 21559 Ecosystem Monitoring and Assessment Project Completed 2015 Benthic habitats play vital roles in the distribution and abundances of marine resources. Understanding how fish populations respond to variability of benthic habitat characteristics is essential for effective coral reef management and monitoring. A pilot study was conducted by NOAA Pacific Islands Fisheries Science Center (PIFSC) Coral Reef Ecosystem Program (CREP) to examine the relationships and linkages between the geomorphological benthic characteristics and fish demographics in Tutuila, American Samoa and the analysis was later expanded to the main Hawaiian Islands. Geomorphological metrics characterizing benthic habitats including slope, rugosity, curvature, and convexity were derived using best available bathymetry for each area. The fish assemblages and abundance data were collected during Rapid Ecological Assessment (REA) surveys from 2010 to 2016. These fish data were collected according to a stratified random survey design using depth as an environmental correlate. Based on the analysis for Tutuila, American Samoa, preliminary evidence was found that using both depth and convexity to define strata may result in more precise estimates of fish biomass. This analysis was expanded to the main Hawaiian Islands for the subsequent year of the project, and found that including several other metrics in CREP's sampling design can enhance the estimates of fish biomass. Results and data from the analysis for Tutuila, American Samoa can be accessed online via the Pacific Islands Benthic Habitat Mapping Center website at http://www.soest.hawaii.edu/pibhmc/pibhmc_documentation.htm#other_pubs. The PIFSC administrative report from the analysis for the main Hawaiian Islands is in review as of Aug 2017 and will be available on the PIFSC website once published at https://www.pifsc.noaa.gov/library/staff_publications.php. This multi-year project is funded by NOAA Coral Reef Conservation Program (CRCP) and the analysis informs efforts to improve reef monitoring and management, and determines which geomorphological characteristics are most effective for predicting fish populations. It also supports the operational needs of NOAA Coral Reef Ecosystem Program’s field data collection. Gorospe K, Acoba A. In Review.

Two datasets collected by NOAA Coral Reef Ecosystem Program (CREP) were used for Tutuila, American Samoa. Gridded bathymetry compiled from multibeam data collected in 2004 and 2006 was used to derive geomorphological data including aspect, slope, rugosity, curvature, and convexity. The other dataset is in-situ fish demographic data collected under the Pacific Reef Assessment and Monitoring Program and the NOAA National Coral Reef Monitoring Program between 2010 and 2015. Gridded bathymetry and geomorphological data were then spatially correlated to the fish demographic data. For the main Hawaiian Islands, LiDAR (Light Detection and Ranging) collected by U.S. Army Corps of Engineers (USACE), JALBTCX (Joint Airborne Lidar Bathymetry Technical Center of eXpertise) in 2013 were used to derive geomorphologic data. In addition to the metrics generated for Tutuila, slope of slope was also derived for the main Hawaiian Islands. The in-situ fish demographic data were collected between 2010 and 2016. Geomorphological data inherit the accuracy of the source gridded bathymetry. The attribute and positional accuracies of the gridded multibeam bathymetry for Tutuila, American Samoa are reported in the metadata which can be found at http://www.coris.noaa.gov/metadata/records/html/tutuila_5m.html. The accuracies of the gridded LiDAR data can be found for each island in the main Hawaiian Islands at https://coast.noaa.gov/htdata/lidar1_z/geoid12a/data/. For the fish demographic data, researchers are trained to identify and estimate/measure the size of fish. Both classroom and field training and tests must be completed for all researchers before each round of surveys begins. This training ensures that the surveys are conducted consistently by all researchers within survey efforts and also across periodic survey efforts. Fish demographic data used for this analysis were collected in 2010, 2012, and 2015 for Tutuila, American Samoa, and 2010, 2012, 2013, 2015 and 2016 for the main Hawaiian Islands. The target precision for these surveys is large enough (e.g., Coefficient of Variation less than 20%) that inter-annual change would likely only be detectable on a decade timescale. Therefore, all survey years used in this analysis are likely comparable, but could easily be addressed by running the analysis separate for all years. For Tutuila, American Samoa, multibeam bathymetry data were not available for shallow areas where the NOAA Ship Hi'ialakai (a 218-foot research ship) or R/V Acoustic Habitat Investigator (a 25-foot survey launch) were not able to access. Bathymetry derived from multispectral IKONOS satellite imagery was investigated for shallow areas to fill gaps; however, bathymetry derived from IKONOS imagery was not included in the analysis due to uncertainty of the attribute accuracies. Therefore, the fish demographic data collected in areas where multibeam bathymetry data is not available (i.e., shallow areas generally less than 6 meter depths) were omitted from the analysis. For the main Hawaiian Islands, LiDAR data were not available for Niihau and Kahoolawe islands, and parts of Lanai and Big islands. The fish sites surveyed in the areas where there is no LiDAR data available were removed from the analysis. The target Coefficient of Variation (CV) for fish demographic data reported at the island-level is 20%. This is only a preliminary analysis of the relationship between geomorphological data and fish biomass. For Tutuila, American Samoa, Convexity was chosen for further analysis based on a qualitative assessment. Due to the incompleteness of the bathymetry data in Tutuila, American Samoa described in the “Completeness Measure” section, ideally the analyses should be conducted for a location where bathymetry data is available for shallow areas. For the main Hawaiian Islands, Rugosity, Slope, Slope of Slope and Profile Curvature were chosen for the further analysis. All geomorphological data were derived using SAGA. Some data were cross-checked with data derived using ArcGIS and the Benthic Terrain Modeler (BTM) ArcGIS extension. Sanity checks were performed to examine the process of spatially correlating the gridded bathymetry and geomorphological data with fish demographic data.

U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-64, 35 p. 2 The first step was to generate a series of geomorphology benthic variables from multibeam bathymetry for the nearshore environment of Tutuila, American Samoa using open source GIS software, System for Automated Geoscientific Analyses (SAGA) 2.1.4. Six geomorphology variables were derived for this study. Detailed descriptions of the tools used are available in Watkins (2015). Slope, aspect and profile curvature were derived from the multibeam bathymetry with the Slope, Aspect, Curvature tool in SAGA using the default option of the nine parameter 2nd order polynomial method. Real surface area was derived using the Real Surface Area tool in SAGA, which was then also used to calculate rugosity, a measure of roughness, derived by dividing real surface area by the geometric surface area. Terrain surface convexity is measured as the percentage of convex-upward cells within a constant radius of ten cells. The terrain surface convexity tool in SAGA was used to derive this variable. Watkins, R. 2015. Terrain Metrics and landscape Characterization from Bathymetric Data; SAGA GIS Methods and Command Sequences. Internal Report 3 For each of the benthic geomorphology variables, site-specific values were extracted for each fish survey location in Tutuila using the Sample tool available in Esri's ArcToolbox. In addition, geomorphology values were averaged across all cells within the available data within a radius of 30, 50, and 100 meters from the fish survey site. The Buffer tool in Esri's ArcToolbox was used to create the zone shapefile with the radius of 30, 50, and 100 meters of each fish survey site. The Zonal Statistics tool in Esri's ArcToolbox was then used to generate the mean value for each geomorphology variable for each site.

Based on this, convexity was chosen as a promising geomorphology metric that could potentially be informative for surveying fish biomass. Using the scatterplots and trend lines as a guide, bin boundaries for high, moderate, and low convexity were selected.

A preliminary analysis examining linkages between reef fish assemblages and benthic habitat characteristics in Tutuila, American Samoa. Internal Report 7 Sampling design performance was evaluated for each fish biomass metric, by calculating n* (i.e., the number of samples required to attain a target coefficient of variation). This was done for two sampling designs: (1) using depth as a covariate for stratification and (2) using a combination of depth and convexity as covariates for stratification.

A preliminary analysis examining linkages between reef fish assemblages and benthic habitat characteristics in Tutuila, American Samoa. Internal Report 8 Steps 1-3 were repeated for the main Hawaiian Islands with the LiDAR data acquired by U.S. Army Corps of Engineers (USACE), JALBTCX (Joint Airborne Lidar Bathymetry Technical Center of eXpertise). The gridded LiDAR data were downloaded from the NOAA Data Access Viewer (https://coast.noaa.gov/dataviewer/#/). In addition to the geomorphologic metrics derived for Tutuila, American Samoa, Slope of Slope was also derived for the main Hawaiian Islands. Due to the large file size of the LiDAR data, the method to calculate the mean and standard deviation values of the metrics for each site was modified by calculating focal mean and standard deviation using Focal Statistics tool in ArcToolbox at radius of 30m, 50m and 100m before assigning value to each site.

U.S. Dept. of Commerce, NOAA Technical Memorandum NOAA-TM-NMFS-PIFSC-64, 35 p. 9 Steps 4-5 were repeated for the fish demographic data collected for the main Hawaiian Islands between 2010-2016 with the associated geomorphologic metrics derived from LiDAR. It is found that the means of rugosity, slope, and slope of slope, and standard deviation of profile curvature has correlations with fish biomass metrics, and further analysed to derive n* described in Steps 6-7.
