Preparing for our travels, whether near or far, we have probably worried about a series of tasks, ranging from checking the mo- tor oil, to the maintenance of our bicycle or, as you prefer, skateboard. In await of leaving, we have !nally taken on the series of Q/3'-3()"D,99,</3)3 tedious chores and things to organise. We’ve tidied up the garden and the toolshed, while the more fortunate among us have ?*3-%/ started the maintenance of their swimming pool... Staring dreamily at those crystal waters, our thoughts drift to our next dive, be it this weekend, next week or the upcoming one. But then why, after the long winter “hibernation”, don’t we devote as much attention to the maintenance of our diving equip- ment and to the review of dive procedures? It will only be time well spent, believe me. That’s why, to better enjoy this summer, Alert Diver has included two full articles, devoted to the return to the diving season: When The Buddy System Fails, in the Prepared Diver section, and Getting Ready for the Dive Season, in the Incident Insights section. Instead, if you’ve planned to stay home, I recommend reading Deep Adventure (Features section). While comfortably sinking in the folds of your favorite chair, you can follow an incredible adventure into the deep, aboard a small “pocket submarine”. Since diving is not just about procedures, diving tables and tedious calculations, we can have fun reading the new section PFO for Dummies. Now you can take us divers less seriously and, with your dive knowledge, get a di"erent perspective on even the most di#cult topics of dive medicine and physiology, with satire and humor. I wish you a great Summer, and the best dives, with DAN at your side! +8EE#?%;c& /#>B%(8?;c *E>("S& #C(%8$d>"#$%C()#$F#7 T N&KO&9,7:(;<3=28=(,./,> "#$$#%&!$'!$(#!#)*$'% Lost at Sea...

  • A Bayesian Latent Allocation Model for Clustering Compositional Data with Application to the Great Barrier Reef
    A Bayesian latent allocation model for clustering compositional data with application to the Great Barrier Reef Luiza S.C. Piancastelli1,∗ Nial Friel1;2†, Julie Vercelloni3‡, Kerrie Mengersen3§ and Antonietta Mira4¶ 1School of Mathematics and Statistics, University College Dublin, Dublin, Ireland 2Insight Centre for Data Analytics 3School of Mathematical Sciences, Queensland University of Technology, Brisbane, Queensland, Australia 4Data Science Lab, Università della Svizzera italiana, Lugano, Switzerland Abstract Relative abundance is a common metric to estimate the composition of species in ecological sur- veys reflecting patterns of commonness and rarity of biological assemblages. Measurements of coral reef compositions formed by four communities along Australia’s Great Barrier Reef (GBR) gathered between 2012 and 2017 are the focus of this paper. We undertake the task of finding clusters of tran- sect locations with similar community composition and investigate changes in clustering dynamics over time. During these years, an unprecedented sequence of extreme weather events (two cyclones and two coral bleaching events) impacted the 58 surveyed locations. The dependence between constituent parts of a composition presents a challenge for existing multivariate clustering approaches. In this arXiv:2105.02140v1 [stat.AP] 5 May 2021 paper, we introduce a new model that is a finite mixture of Dirichlet distributions with group-specific parameters, where cluster memberships are dictated by unobserved latent variables. The inference is carried in a Bayesian framework, where Markov Chain Monte Carlo strategies are outlined to sample from the posterior model. Simulation studies are presented to illustrate the performance of the model in a controlled setting. The application of the model to the 2012 coral reef data reveals that clusters ∗Corresponding author.

Comparison of two photographic methodologies for collecting and analyzing the condition of coral reef ecosystems. Ecosphere 8(10):e01971. 10.1002/ecs2.1971 Abstract. Coral reefs are declining rapidly in response to unprecedented rates of environmental change. Rapid and scalable measurements of how benthic ecosystems are responding to these changes are critically important. Recent technological developments associated with the XL Catlin Seaview Survey have begun to provide high-resolution 1-m2 photographic quadrats of ~1.8–2 km of coral reefs at 10 m depth by using a semi-autonomous image collection SeaView II camera system (SVII). The rapid collection of images by SVII can result in images being taken at a variable distance (1–2 m) from the substrate as well as having natural light variability between images captured.

At these events, 360-degree viewers were also provided to share immersive underwater imagery and video captured in Timor-Leste.

Exploring Tara Bandu Four villages were visited on the island of Ataúro to explore Tara Bandu: Adara, Beloi, Biqueli, and Villa. I was shocked to see some of the Tara Bandu marine protected areas were very barren with little coral. The intertidal reef flats were also generally stripped down as gleaning, or collecting of organisms, is an im- portant means of subsistence. These village stays also afforded a glimpse into life in the village. Some communities all fish together in the morning. Beloi is the biggest village on the island with the most ‘diversified’ economy including a network of homestays of eight households providing accomodation for guests.

  • Monitoring Through Many Eyes: Spatially Enabling People to Protect the Great Barrier Reef
    Monitoring Through Many Eyes: Spatially enabling people to protect the Great Barrier Reef Stage 2 – Report 1/4 Summary document About us About The Monitoring Through Many Eyes project is a multidisciplinary research effort designed to enhance the monitoring of the Great Barrier Reef. The project aims to create a virtual reef by geotagging underwater photos and videos contributed through citizen science. These will be used to create immersive environments that will help to improve estimates and predictions of the health of the Reef. Our mission is to deliver new know-how in visualisation and spatial statistical modelling, new spatial products, and a new avenue for the public to engage in monitoring the reef.
