    Arrow squids of the genjis Nototodarus in New Zealand waters: systematics, biology, and fisheries (1987)
    Taylor & Francis
    In:  New Zealand Journal of Marine and Freshwater Research , 21 . pp. 315-326.

    Description: Two species of arrow squid, Nototodarus (Oegopsida: Ommastrephidae), are caught in New Zealand waters. The close similarity in most morphometric characters has lead to confusion over the status of the two species. They are distinguished by the number of pairs of suckers on the first right arm; adult males are distinguished by the number of proximal tubercles and the morphology of the distal part of the hectocotylised arm; fresh or frozen specimens can be identified by gel elec‐trophoresis of the enzyme glycerol‐3‐phosphate dehydrogenase. Nototodarus sloanii is found in southern waters and N. gouldi in more northerly waters around New Zealand as well as southern waters of Australia. Differences between the two species are described and notes presented on their biology, abundance, and exploitation.

    Satellite measurements of sea surface cooling during hurricane Gloria (1987)
    Nature Publishing Group

    Description: Hurricanes and other strong storms can cause important decreases in sea surface temperature by means of vertical mixing within the upper ocean, and by air–sea heat exchange. Here we use satellite-derived infrared images of the western North Atlantic to study sea surface cooling caused by hurricane Gloria (1985). Significant regional variations in sea surface cooling are well correlated with hydrographic conditions. The greatest cooling (up to 5°C) occurred in slope waters north of the Gulf Stream where the seasonal thermocline is shallowest and most compressed; moderate cooling (up to 3 °C) occurred in the open Sargasso Sea where the thermocline is deeper and more diffused; little or no cooling occurred in shallow coastal waters (bottom depth less than 20 m) which were isothermal before the passage of hurricane Gloria. There is a pronounced right-side asymmetry of sea surface cooling with stronger (by a factor of 4) and more extensive (by a factor of 3) cooling found on the right side of the hurricane track. These qualitative results are consistent with the notion that vertical mixing within the upper ocean is the dominant sea surface cooling mechanism of hurricanes.

    Food and feeding of Loligo vulgaris reynaudiifrom St. Francis Bay, South Africa (1987)
    Taylor & Francis
    In:  South African Journal of Marine Science, 5 (1). pp. 557-564.
    Details
    Publication Date: 2020-05-26
    Description: Change of colour, consistency and pH in contents of the caecum and the stomach of laboratory-maintained long-finned squid Loligo vulgaris reynaudii were determined. There was relatively little variability in any of these parameters of the specimens investigated. Colour and consistency of food or emulsion were used as a basis of analysis of stomach-caecum contents of wild squid. Most squid fed late during the night and/or during the early morning, and the frequency of caecum colour categories did not change much between trawls. Wild squid preyed upon different organisms according to their size. Squid of 69–125 mm dorsal mantle length fed mainly on euphausiids (95% by frequency of occurrence, 87,5% by mass) and those of 126–240 mm mainly on fish (78 and 74,3% respectively) with Bregmaceros?macclellandii and hake as important components. Unidentified fish in the stomachs (i.e. those from which no otoliths were available) probably also belonged to these two species.

    Publication Date: 2016-06-10
    Description: There is now clear evidence that changes in the Earth's climate may be sudden rather than gradual. It is time to put research into the build-up of carbon dioxide in the atmosphere on a better footing.
