The Submillimetre Common User Bolometer Array 2 (SCUBA-2) is the James Clerk Maxwell Telescope's continuum imager, operating simultaneously at 450 and 850~$\mu$m. SCUBA-2 was commissioned in 2009--2011 since that time, regular observations of point-like standard sources have been performed whenever instrument use. Expanding calibrator observation sample by an order magnitude compared to previou...

We have measured the contribution of submillimeter and mid-infrared sources to the extragalactic background radiation at 70 and 160μm. Specifically, we have stacked flux in 70 and 160μm Spitzer Space Telescope (Spitzer) observations of the Canada-UK Deep Sub-millimeter Survey 14h field at the positions of 850μm sources detected by SCUBA and also 8 and 24μm sources detected by Spitzer. We find t...

We have measured the contribution of submillimeter and mid-infrared sources to the extragalactic background radiation at 70 and 160μm. Specifically, we have stacked flux in 70 and 160μm Spitzer Space Telescope (SST) observations of the Canada-UK Deep Sub-millimeter Survey 14h field at the positions of 850μm sources detected by SCUBA and also 8 and 24μm sources detected by the SST. We find that ...

The depths from 10 to 30 m are usually not considered narcotic in scuba air-diving, and evidence of psychomotor disturbances attributable to nitrogen narcosis at these depths is weak and contradictory. 15 experienced male divers were tested in a chamber at 1, 2, 3, and 4 bars over five consecutive days using a battery of computer generated psychological tests-Computerized Reactionmeter Drenovac...

We present a 1200-μm image of the Great Observatories Origin Deep Survey North (GOODSN) field, obtained with the Max Planck Millimeter Bolometer array (MAMBO) on the IRAM 30-m telescope. The survey covers a contiguous area of 287 arcmin to a near-uniform noise level of ∼0.7 mJy beam. After Bayesian flux deboosting, a total of 30 sources are recovered (>3.5-σ). An optimal combination of our 1200...

Recent observations of galaxy clusters with the SCUBA instrument on the James Clarke Maxwell Telescope have revealed a sample of gravitationally lensed sources at sub-mm wavelengths. We extend our previous calculation on the expected number of lensed optical arcs and radio sources to study the sub-mm lensed source statistics due to foreground massive clusters. For a flat cosmology with Ωm = 0.4...

Current state of <i>Chlamys swiftii</i> settlements and resources this species in the coastal waters Primorye (Japan Sea) are considered on base surveys conducted 2007–2021. The data spatial distribution abundance scallops were obtained by methods scuba counts at depth < 20 m. total biomass calculated using Voronoi diagrams (Thiessen polygons). In total, analyzed for 13457 statio...

We present sensitive 850μm SCUBA photometry of a statistically-complete sample of six of the most luminous (MB < −27.5; νLν(1450 Å) >∼ 10 13 L⊙), z > 4 radio-quiet quasars, reaching noise levels (1σ ∼ 1.5mJy) comparable with the deep blank sky surveys. These observations probe the rest frame far infrared region (∼150μm), at luminosity levels for thermal sources comparable with those that IRAS p...
