Site summary
Read this summary in:

Totoya is a horseshoe-shaped volcanic island in Fiji's Lau group whose drowned caldera forms a near-enclosed lagoon, and nine expedition transect stations around the island recorded 12-46% hard coral cover; Anderson's photographs and the transect data from these dives are on the nine station pages (FJTO01-FJTO09). The Fiji region has averaged 8.9 DHW in recent years, above the severe-bleaching threshold, and Fiji lies within the South Pacific cyclone belt.

Site description

Setting

Totoya is a horseshoe-shaped volcanic island in the Moala Group of Lau Province, its drowned caldera forming a near-enclosed lagoon.

Coral cover

Stressors

Regional thermal context: the NOAA Coral Reef Watch Fiji virtual station has averaged an annual maximum of 8.9 degree heating weeks across 2021-2025 (NOAA Coral Reef Watch), above the 8 DHW threshold at which severe bleaching and mortality are expected, and Fiji lies within the South Pacific cyclone belt. That is stated as background for the region, not as an observation at Totoya.

Comparisons with other data

Wilson et al. (2008) surveyed this site (Totoya) in 2000 and 2006. If you have survey data from this site to share, please email us.
