Abstract:
This raster denotes predicted habitat suitability for Leptoseris in the Au'au Channel region. Maximum Entropy (MaxEnt) modeling software was used to create this ensemble model, which is an average of 10 model replicates. MaxEnt works by analyzing the distribution of environmental variables where species are present, so it can find other areas that meet all of the same environmental constraints. Georeferenced records containing information about mesophotic coral occurrence and environmental predictors describing the seafloors depth, vertical structure, available light, surface temperature, currents and distance from shoreline were used to train MaxEnt. Model performance and accuracy were assessed using Receiver Operating Characteristic (ROC) Area Under the Curve (AUC) and a randomly chosen, spatially independent data subset. The average test AUC for this predictive ensemble model was 0.93, and the producers accuracy of this ensemble predictive model was 78.2% (when the habitat suitability threshold = 0.2). The habitat suitability threshold of 0.2 represents the sum of the maximum ROC sensitivity and specificity values. Extreme care should be taken when selecting a habitat suitability threshold because it affects the probability of correctly identifying the presence and absence of mesophotic corals. For more information describing how this predictive surface was developed and its limitations, please see the following website: <http://ccma.nos.noaa.gov/ecosystems/sanctuaries/hwnms/> This dataset is located between the islands of Maui, Lanai, Molokai and Kahoolawe, and includes the Au'au Channel as well as parts of the Kealaikahiki, Alalakeiki and Kalohi Channels.
Purpose:
This dataset describes the predicted distribution of Leptoseris in the Au'au Channel region in the Main Hawaiian Islands (MHI). Leptoseris are mesophotic hard corals, which are light-dependent corals adapted to the low light conditions at approximately 30 to 150 m in depth. Several physical factors potentially influence their spatial distribution, including aragonite saturation, alkalinity, pH, currents, water temperature, hard substrate availability and the availability of light at depth. Mesophotic corals and mesophotic coral ecosystems (MCEs) have increasingly been the subject of scientific study because they are being threatened by a growing number of anthropogenic stressors. They are the focus of this spatial modeling effort because the Hawaiian Islands Humpback Whale National Marine Sanctuary (HIHWNMS) is exploring the expansion of its scope beyond the protection of the North Pacific Humpback Whale (Megaptera novaeangliae) to include the conservation and management of these ecosystem components. The present study helps to address this need by examining the distribution of mesophotic corals in the Au'au Channel region.
