    Longline Observations
    2. A total of 31 longline cruises were conducted within the CAMLR Convention Area during
    2009/10, with scientific observers (international and national) aboard all vessels. At the time of
    writing this paper, one cruise in subarea 58.5.2 was still at sea. Nine cruises were undertaken in
    Subarea 48.3 by 9 vessels, two cruises were undertaken in Subarea 48.4 by 2 vessels, three cruises
    was undertaken in Subarea 48.6 and Divisions 58.4.1, 58.4.2, 58.4.3a and 58.4.3b by 3 vessels, 3
    cruises were conducted by 2 vessels in Division 58.5.2 (one still at sea), one cruise was conducted in
    Subareas 58.6 and 58.7 and Area 51, and 13 cruises were undertaken in Subareas 88.1 and 88.2 by 12
    vessels.
    3. Throughout this paper the data reported are those that have been collected by scientific
    observers and unless specified does not include data collected by the crew. A detailed list of the
    observations conducted and the types of data submitted to the Secretariat is contained in Table 1.
    Incidental Mortality
    4. The observed seabird catch rates are calculated using the total numbers of hooks observed and
    the total observed seabird mortality (Table 2). Two seabird mortalities were observed on the Tronio
    in Subarea 48.3, a grey-headed albatross (Thalassarche chrysostoma) and a Southern black-browed
    albatross (T. melanophrys). Two Cape petrels (Daption capense) mortalities were observed on the
    Austral Leaser II in Division 58.5.2.
