    Notes: The v=1–0 vibration–rotation transitions in the X 2Π and a 4Σ− states as well as those between the two electronic states were observed with a difference frequency laser as a radiation source. The two electronic states (X 2Π and a 4Σ−) lie close together and interact each other strongly through the spin–orbit coupling. A merged least-squares fit was carried out with the present infrared transition wave numbers, some of the previous optical term values, and the recent far-infrared rotational transition frequencies to determine the spectroscopic parameters precisely. The equilibrium internuclear distance was obtained to be 1.0692±0.0002 and 1.0924±0.0001 A(ring) for the X and a states, respectively. The Λ-type doubling transition frequencies were calculated for several of the lowest J states with the molecular constants obtained and the hyperfine coupling constants determined from the far-infrared transitions.

    A light trap to collect krill and other micronektonic and planktonic animals under the Antarctic coastal fast ice (1986)

    Notes: Summary Under the Antarctic coastal fast ice a light trap proved to be promising device for collecting not only planktonic animals, but also micronektonic animals like krill which have been rarely collected with tow nets. Sampling was conducted at night from May through November, 1984 in Kitano-ura Cove off the East Ongul Island in Lützow-Holm Bay. Design of the gear and the sampling procedure are described. A total of 37 samplings were made that resulted in the collection of seven species of copepods, eight species of amphipods, three forms of notothenid fish larvae, two species each of euphausiids and polychaetes, and one species each of mysid, cumacean, isopod and tanaid crustaceans. All were collected in satisfactory condition for laboratory experiments. During the winter Euphasia superba was found to be benthopelagic and it probably feeds on detritus on the sea floor at about 40 m depth under the ice.
