- Abstract:
-
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.
This map denotes predicted habitat suitability for all mesophotic corals 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 0.9, and the overall accuracy of this ensemble predictive model
was 73.1% (when the habitat suitability threshold = 0.25). The habitat suitability threshold of
0.25 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:

- Purpose:
-
This dataset describes the predicted distribution of all mesophotic corals in the Au'au Channel
region in the Main Hawaiian Islands (MHI). Mesophotic hard corals 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.
