Photic stress on coral reefs in the Maldives: The Amphistegina bleaching index

Arthur Adams, Aurélie Angéloz, Anaël Lehmann

The Amphistegina Bleaching Index (ABI) was applied to three Maldivian reefs in the Rasdhoo and North Ari Atolls in 2018, during normal sea surface temperature conditions. This dataset was then compared with a 2015, pre-coral bleaching study. The results pr ...

Responses of reef bioindicators to recent temperature anomalies in distinct areas of the North Ari and Rasdhoo atolls (Maldives)

Arthur Adams, Aurélie Angéloz, Anaël Lehmann

Assessments of reef sediments in the North Ari Atoll (Maldives) were conducted in 2015 and 2018 on reefs of three islands with different management strategies: community, resort, and uninhabited. Indices applied were the Foraminifera in Reef Assessment and ...

Photoacclimatory and photoprotective responses to cold versus heat stress in high latitude reef corals

Thomas Krüger

Corals at the world's southernmost coral reef of Lord Howe Island (LHI) experience large temperature and light fluctuations and need to deal with periods of cold temperature (< 18 °C), but few studies have investigated how corals are able to cope with thes ...

UAV based multispectral imaging over a lagoon with corals in Reunion Island

Martin Rehak, Yosef Akhtman, Dragos Constantin, Harold Gabriel Eugène Justin Clenet

A UAV-based hyperspectral survey was carried out in September 2014 over the fringing reef of l’Ermitage, Saint Gilles, Reunion Island. This site is of particular interest because it shows signs of major erosion and is subject to sudden flooding occuring du ...

Discovery of a second kilohertz quasi-periodic oscillation peak in 4U 1608-52

Demetri Psaltis

Using a new technique to improve the sensitivity to weak quasi-periodic oscillations (QPOs), we discovered a new QPO peak at about 1100 Hz in the March 1996 outburst observations of 4U 1608-52, simultaneous with the similar to 600-900 Hz peak previously re ...

Kilohertz quasi-periodic oscillation and atoll source states in 4U 0614+09

Demetri Psaltis

We report three RXTE/PCA observations of the low-mass X-ray binary 4U 0614+09. They show strong (similar to 30% rms) band-limited noise with a cutoff frequency varying between 0.7 and 15 Hz in correlation with the X-ray flux, f(x). We observe two nonsimult ...
