We report IRAM Plateau de Bure, millimeter interferometry of three z ∼2.4 to 3.4, SCUBA deep field galaxies. Our CO line observations confirm the rest-frame UV/optical redshifts, thus more than doubling the number of confirmed, published redshifts of the faint submillimeter population and proving their high-z nature. In all three sources our measurements of the intrinsic gas and dynami-cal mass...

BACKGROUND Recreational scuba diving involves the use of complex instruments and specialized skills in an unforgiving environment. Errors in dive preparation in such an environment may lead to unsafe conditions, mishaps, injuries and fatalities. Diving mishaps can be major and minor based on their potential to cause injury and the severity of the resulting injury. The objective of this study is...

In recent decades, spearfishing with SCUBA has emerged as an efficient method for targeting reef fish in deeper waters. However, deeper waters are increasingly recognised as a potential source of refuge that may help sustain fishery resources. We used a combination of historical catch data over a 20-year time period and fishery-independent surveys to investigate the effects of SCUBA spearfishin...

In recent years, scuba diving has become accessible worldwide. The average age of female scuba divers is similar to their window of fertility, and many women dive annually without knowing their pregnancy status. These women seek advice concerning the potential teratogenicity of diving, and whether they can continue the pregnancy. Nevertheless, little is known about the consequences of scuba div...

Observations using SCUBA reveal that macroscopic organic aggregates produced by appendicularians reached densities of 44 to 1,130 m-’ in the Gulf of California. Though these aggregates constituted less than 5% of total particulate carbon, their carbon : nitrogen ratio was twice that of particles in the surrounding seawater. The C : N ratio of the total particulate matter increased directly with...

BACKGROUND Immersion pulmonary edema is potentially a catastrophic condition; however, the pathophysiological mechanisms are ill-defined. This study assessed the individual and combined effects of exertion and negative pressure breathing on the cardiovascular system during the development of pulmonary edema in SCUBA divers. METHODS Sixteen male professional SCUBA divers performed four SCUBA d...

We present the results of simultaneous 450 $\mu$m and 850 polarization observations toward massive star forming region NGC 2071IR, a target BISTRO (B-fields in Star-Forming Region Observations) Survey, using POL-2 polarimeter SCUBA-2 camera mounted on James Clerk Maxwell Telescope. find pinched magnetic field morphology central dense core region, which could be due to rotating toroidal disk-lik...

Obscured AGNs are thought to contribute a large fraction of the hard X-ray background (2–10 keV), and have also been proposed as the powerhouse of a fraction of the SCUBA sources which make most of the background at 850μm, thus providing a link between the two spectral windows. We have tackled this issue by comparing data at 2–10 keV and at 850μm for a sample of 34 sources at fluxes (or limitin...

The purpose of this study was to record the species of Antipatharia on Jamaican reefs and to carry out limited studies on densities and sizes of the common species. In addition, a cliff face created by dredging in 2002 provided the opportunity to study growth of newly settled colonies. Observations since 1998 and measurements since 2001 were made using SCUBA at depths down to 35 m. Seven specie...

An open-circuit scuba diver’s acoustic signature (radiated sound) consists predominately of a sequence of regularly spaced wideband pulses each corresponding to the inhaling phase of the diver’s breathing cycle. A cyclic frequency analysis of the output signal from a single hydrophone leads to the automated detection of the diver and an estimate of the diver’s breathing rate. Measurement of the...
