Site summary
Read this summary in:

White Sands produced a strong current, with fish blanketing the reef before a run-out onto a white sand slope with soft corals. No cover of its own was measured; the nearest survey station, Reef Check's Mawan (Sector 1) 0.91 km away, recorded 3.1% hard coral in August 2020, while 2020 station means within 2 km ranged from 8.8% to 51%, showing how patchy this stretch of reef is.

Stressors

No bleaching, disease, or other stressor is recorded for this dive (15 August 2009) in Anderson's dive log or the 2009 trip notes.

Comparisons with other data

All five Reef Check stations within 2 km were surveyed in 2020, and their 2020 station means in the survey table span 8.8-51%: Mawan (Sector 1) 10% (the mean of its two 2020 surveys, the newer of which is the 3.1% on the tile) and Mawan (Sector 2) 8.8%, both 0.91 km away; Siaba Besar (Sector 1) 51% and Siaba Besar (Sector 2) 47% (the mean of its two 2020 surveys), both 1.51 km away; and Pengah Kecil (Sector 1) SW Side 48% at 1.73 km. A spread that wide inside 2 km in one season means none of these figures is this site's own cover.

Dive record

One dive, 15 August 2009, entering at 10:45 for 65 minutes to 21.3 m with a divemaster.

Other notes

The log records a strong current, fish blanketing the reef, and a run-out onto a white sand slope with soft corals.

Within 5 km, 6 independent survey stations recorded hard coral cover in 10 surveys between 2016 and 2020. The most recent nearby survey is from 2020, so these values predate recent heat stress.

Collected by other programs using different methods (Reef Check uses point-intercept transects), so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once, the cell shows either the range of its values or, as a single value, the mean of surveys made in one year. Station names are not dive-site names.
