Data on environmental contaminants in sea turtle eggs at Venu Island, Kaimana - West Papua, Indonesia.

ABSTRACT: Long-range atmospheric transport of contaminants can result in contamination of aquatic systems in otherwise pristine areas. Contaminants enter aquatic systems largely as inorganic pollutants that often are microbially transformed. The result can be a potent neurotoxin with a strong tendency to biomagnify within food chains. The general human population is exposed to contaminants such as mercury, predominantly through food consumption. Here, we report data on contaminants from a sample of green and hawksbill turtle that were sampled from a subset of two nests during the 2016 nesting season at Venu Island, Kaimana. Three contaminants (mercury, cadmium, arsenic) found in eggs exceeded safety limits for human consumption. Other contaminants such as lead, zinc, manganese, copper and iron were found below the established safety standard.

Project description:BackgroundProviding coral reef systems with the greatest chance of survival requires effective assessment and monitoring to guide management at a range of scales from community to government. The development of rapid monitoring approaches amenable to collection at community level, yet recognised by policymakers, remains a challenge. Technologies can increase the scope of data collection. Two promising visual and audio approaches are (i) 3D habitat models, generated through photogrammetry from video footage, providing assessment of coral cover structural metrics and (ii) audio, from which acoustic indices shown to correlate to vertebrate and invertebrate diversity, can be extracted.MethodsWe collected audio and video imagery using low cost underwater cameras (GoPro Hero7™) from 34 reef samples from West Papua (Indonesia). Using photogrammetry one camera was used to generate 3D models of 4 m2 reef, the other was used to estimate fish abundance and collect audio to generate acoustic indices. We investigated relationships between acoustic metrics, fish abundance/diversity/functional groups, live coral cover and reef structural metrics.ResultsGeneralized linear modelling identified significant but weak correlations between live coral cover and structural metrics extracted from 3D models and stronger relationships between live coral and fish abundance. Acoustic indices correlated to fish abundance, species richness and reef functional metrics associated with overfishing and algal control. Acoustic Evenness (1,200-11,000 Hz) and Root Mean Square RMS (100-1,200 Hz) were the best individual predictors overall suggesting traditional bioacoustic indices, providing information on sound energy and the variability in sound levels in specific frequency bands, can contribute to reef assessment.ConclusionAcoustics and 3D modelling contribute to low-cost, rapid reef assessment tools, amenable to community-level data collection, and generate information for coral reef management. Future work should explore whether 3D models of standardised transects and acoustic indices generated from low cost underwater cameras can replicate or support 'gold standard' reef assessment methodologies recognised by policy makers in marine management.
