    Description: Strandings of the giant squid, Architeuthis monachus (Steen-strup), have always stirred attention because of the rarity and enormous size of these cephalopods. These animals have never been observed in their natural habitat and little is known about their physiology and ecology. Stranding of giant squids in Newfoundland waters has been correlated with the inflow of warm water, suggesting that increased temperature may be causing their death1. Squids have also been carried to the Norwegian coast with the warm North Atlantic current2 and on 23 August 1982 a live specimen was caught off Radöy near Bergen, Norway (Fig. 1). This catch gave an unprecedented opportunity to study the effects of temperature on the oxygen binding properties of blood from the giant squid. The present finding of an excess of a fourfold decrease in O2 affinity when temperature is increased from 6.4 to 15°C strongly suggests that giant squids may suffocate from arterial desaturation when increased ambient temperatures are experierced.

    Description: Circumpolar surface waters dominate the circulation of the Southern Ocean and sustain one of the ocean's largest standing stocks of biomass thereby producing a significant output of biogenic components, mainly diatoms, to the bottom sediments. Generally transit of biogenic matter from the sea surface to the sea floor affects nutrient regeneration fuels benthic life and transfers signals to the sediment record1–5. Reliable quantification of the relationship between biological production, fractionation of skeletal and tissue components and bottom sediment accumulation depends on direct vertical flux measurements from sediment trap deployments6–9, which have proved to be most scientifically productive10–13. We now present data on vertical mass fluxes from the Southern Ocean and evidence for strong biogeochemical fractionation between organic carbon-, nitrogen- and phosphorus-containing compounds, siliceous and calcareous skeletal remains, and refractory aluminosilicates.

    Description: A subtropical front was observed in the area south and southeast of the Azores during cruises of FS Meteor and FS Poseidon in early 1982. The front has a basically west–east extension, with considerable meandering observed. Meso-scale eddies are found on both sides. The overall flow pattern corresponds to earlier results on geopotential differences in the upper northeast Atlantic, but the baroclinic transport of the order of 107 m3 s−1 is found to be concentrated in a 60-km wide jet. We suggest here that the current band is part of the gyre circulation, resulting from a branching of the North Atlantic Current.

    Description: Basalts from the Reykjanes Ridge contain noble gases delivered from the non-degassed lower mantle by the Iceland plume. These lower mantle gases are thought to be a mixture of planetary and solar components, as would be expected if the Earth accreted from fine silicate particles.

    Notes: [Auszug] TPA, an activator of protein kinase C, triggers platelet aggregation as well as the secretion of [14C]-serotonin from platelets11-13. The response to activation by 1 mM TPA at 37 C, with constant stirring, is more gradual than the response to activation by O.1Uml-1 thrombin and maximal aggregation ...

    Notes: [Auszug] GASKELL REPLIES-While recognizing that the main point of Jordan's comment is to attempt to correct the allegedly misleading generalizations made by Fair all1 and myself2, I must state that the size of the forbidden line emitting region in Fairall 427 is not an open question.

    Notes: [Auszug] THE article on page 756 from Dr P. W. J. Rigby's group at Imperial College is an intriguing document which is plainly of the utmost importance, but for reasons which, at this stage, are not fully apparent. The obvious difficulty is that the observations described bear on such a variety of important ...

    Notes: [Auszug] WRITING some thirty years ago, Hermann Bondi suggested that in astronomy, observations had proven a less reliable arbiter of hypotheses than had theoretical considerations1 . Subsequent historical studies have widened and deepened knowledge of some of the instances cited by Bondi and have uncovered ...

    Notes: [Auszug] THE cellular myc gene may, depending on your point of view, be seen as either the most illuminating or the most confusing of the cellular oncogenes. The promise of illumination lies in the overwhelming circumstantial evidence that c-myc activation in some lymphoid tumours is a direct subversion, ...

    Notes: [Auszug] AFTER some years of increasing interest, rapid progress is now being made in the understanding of lignin biodegradation. Research in a number of laboratories has culminated in the isolation by T.K. Kirk and Ming Tien of a purified enzyme able to depolymerize lignin1. This enzyme, isolated from the ...
