Observation Of Large Diurnal Warming Events In The Near-Surface Layer Of The Western Equatorial Pacific Warm Pool, Alexander Soloviev, Roger Lukas
Observation Of Large Diurnal Warming Events In The Near-Surface Layer Of The Western Equatorial Pacific Warm Pool, Alexander Soloviev, Roger Lukas
Marine & Environmental Sciences Faculty Articles
Because of the relatively calm winds which prevail over the western Pacific warm pool, the diurnal cycle of temperature in the near-surface layer of the ocean is often quite pronounced. During the TOGA Coupled Ocean-Atmosphere Response Experiment (COARE), very high resolution measurements of near-surface thermohaline and turbulence structures were made using bowmounted probes and a free-rising profiler. Experimental data demonstrate a strong dependence of near-surface thermal structure on weather conditions, In calm weather, SST was observed to exceed 33.25°C; this was associated with a diurnal warming of more than 3°C in the top I m of the ocean. A 1-D …
Sharp Frontal Interfaces In The Near-Surface Layer Of The Ocean In The Western Equatorial Pacific Warm Pool, Alexander Soloviev, Roger Lukas
Sharp Frontal Interfaces In The Near-Surface Layer Of The Ocean In The Western Equatorial Pacific Warm Pool, Alexander Soloviev, Roger Lukas

During the TOGA COARE rich horizontal temperature and salinity variability of the near-surface layer of the ocean in the western Pacific warm pool was observed. High-resolution measurements were made by probes mounted on the bow of the vessel in an undisturbed region at ~1.7-m depth during four COARE cruises of the R/V Moana Wave. The authors observed several tens of cases of periodic sharp frontal interfaces of width 1– 100 m and separation 0.2–60 km. The sharp frontal interfaces were often found in frontal regions and on the periphery of freshwater puddles. Maneuvers of the ship were conducted to determine …
A Possible Link Between Coral Diseases And A Corallivorous Snail (Drupella Cornus) Outbreak In The Red Sea, Arnfried Antonius, Bernhard Riegl
A Possible Link Between Coral Diseases And A Corallivorous Snail (Drupella Cornus) Outbreak In The Red Sea, Arnfried Antonius, Bernhard Riegl
Marine & Environmental Sciences Faculty Articles
In April-May and in September 1996, a total of 25 reefs were studied between Taba and Ras Mohammed in the Gulf of Aqaba, Red Sea. In only four of these reefs Drupella cornus showed up in the transects in low numbers and coral diseases were found at a moderate level on most reefs. Only the reefs of Ras umm Sidd, near Sharm el Sheikh exhibited Drupella cornus as well as coral diseases both at abundant or even epidemic levels. There definitely seems to be a correlation between abundance of snail and diseases, but the question of “what comes first” remains …
Discrimination Of Species In The Montastrea Annularis Complex Using Multiple Genetic Loci, Jose V. Lopez, Nancy Knowlton
Discrimination Of Species In The Montastrea Annularis Complex Using Multiple Genetic Loci, Jose V. Lopez, Nancy Knowlton
Marine & Environmental Sciences Faculty Articles
Montastraea annularis, M. franksi and M. faveolata are a complex of recently distinguished coral species whose status remains controversial due to the lack of fixed differences. Here we report on two types of genetic analyses for these taxa: 1) DNA sequences of two nuclear genes [internal transcribed spacers of rDNA (ITS-1, ITS-2) and a ɮ-tubulin intron] and 2) a preliminary screening of the entire nuclear genome using amplified fragment length polymorphisms (AFLP). There was very little variation within or among the three species in DNA sequences. Onlly 3 of 300 nucleotide positions in ITS-1, 3 of the 350 positions …
