Rapid coral mortality following doldrums-like conditions on
Coral bleaching can be induced by many different stressors, however, the most common cause of mass bleaching in the field is high sea temperatures (SST). Here, we describe an unusual bleaching event that followed very calm sea conditions combined with higher than average sea surface temperatures (SST). Patterns of mortality differed from typical thermal bleaching in four ways: 1) mortality was ...
متن کاملTime-varying effects in magnetic mapping: Amphidromes, doldrums, and induction hazard
A magnetic amphidrome is defined as a place where changes of the magnetic field over time, as measured by a total-field magnetometer, are reduced to the point of being negligible. The reduction is caused by destructive interference between the vertical and horizontal components of the time-varying field. At an ideal amphidrome, variations with time are suppressed completely and the total-magnet...

Conservation officials said that the additional funds for...
