We present critical, long-wavelength observations of η Carinae in the submillimetre using SCUBA on the JCMT at 850 and 450 μm to confirm the presence of a large mass of warm dust around the central star. We fit a two-component blackbody to the IR-submm spectral energy distribution (SED) and estimate between 0.3− 0.7 M⊙ of dust exists in the nebula depending on the dust absorption properties and...

concentrations of mn, cd, cr and pb were measured in soft tissues of p. radiata from the hendourabi and lavan islands. forty specimens were collected from each island from the depth 8-10 m using scuba. total, shell and soft tissues weights were measured. mn, cd, cr and pb concentrations of the soft tissues were measured using the atomic absorption technique. a significant difference between spe...

Deep SCUBA surveys have uncovered a population of dust-enshrouded star-forming galaxies at z ≈ 2. Using the ultra-deep 2 Ms Chandra Deep Field-North survey we recently showed that a large fraction of these systems are also undergoing intense black-hole growth. Here we provide further constraints on the properties of the black holes in SCUBA galaxies using the virial black-hole mass estimator. W...

We present a high-resolution millimetre interferometric image of the brightest SCUBAselected galaxy from the Canada-UK deep SCUBA survey (CUDSS). We make a very clear detection at 1.3 mm, but fail to resolve any structure in the source. The interferometric position is within 1.5 arcsec of the SCUBA 850 μm centroid, and also within 1.5 arcsec of a 44 μJy radio source and a very faint, extremely ...

INTRODUCTION An individual case review of diving-related deaths reported to have occurred in Australia in 2004 was conducted as part of the DAN Asia-Pacific dive fatality reporting project. METHOD The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident are provided, and also details from the post-mortem e...

Saba Bank is a large submerged platform (approximately 2200 km(2)), average depth 30 m, located 4 km southwest of Saba Island in Netherlands Antilles, Caribbean Sea. Ships traveling to and from oil terminals on nearby St. Eustatius routinely anchor on the Bank, damaging benthic megafauna. Gorgonian octocorals are vulnerable to anchor damage, and they are common and conspicuous in shallow water ...

Although 70% of the stars in the Galaxy are M-dwarfs, thermal emission searches for cold debris disks have been conducted mostly for A-type and solar-type stars. We report on new λ = 1.2 mm continuum observations of thirty M-dwarfs, using the MAMBO-2 bolometer array camera at the IRAM 30m telescope. For a statistical analysis, we combine these data with our prior SCUBA and MAMBO-2 observations ...

We discuss results from sensitive, wide-field imaging of the millimeter extragalactic background using the Max-Planck Millimeter Bolometer array (MAMBO) at the IRAM 30 m telescope. The detection of a far-infrared and sub-millimeter wavelength background by COBE, and the first sensitive, high-resolution SCUBA images of the sub-mm background have caused significant revisions of our picture of the...

The use of passive acoustics to detect self-contained underwater breathing apparatus (SCUBA) divers is useful for nearshore and port security applications. While the performance of a detector can be optimized by understanding the signal's spectral characteristics, anechoic recording environments are generally not available or are cost prohibitive. A practical solution is to obtain the source sp...

Deep surveys at 850μm from Mauna Kea using the SCUBA camera on the JCMT appear to have discovered a substantial population of ultraluminous infrared galaxies (ULIGs: Lir > 10 L⊙) 3 at high redshift (z ∼ 1−4). The cumulative space density of these sources (∼ 10 deg with S850 > 1mJy) is sufficient to account for nearly all of the extragalactic background light at submillimeter wavelengths. Curren...
