說明

Visual monitoring was conducted from 01/10/2024 to 19/11/2024 during daylight hours for an overall total visual effort of 120.6 hours in the license Block 2913B (which is adjacent to TEEPNA’s Block 2912), located about 290 km from shore in water depths ranging from approximately 2,600 m to 3,300 m, spanning an area of 8,215 km². The forecastle from which most of the observations were done, located on the bow of the vessel, provided a near 180 degrees view and is 13.5 m above sea level. Observations were made with the naked eye, scanning the surface for any visual cues that could indicate the presence of marine fauna (e.g. splashes, white water during calmer periods, waves going against the prevailing direction, dark shapes and the blow/spouts of large whales). High-definition hand-held binoculars with inbuilt compass and reticulation was used to aid in species identification, group size and individual or group behaviour. Range estimation of the initial sightings distance, closest point of approach and final sightings distances were estimated via a calculation converting the reticule scale readings from the reticule binoculars into horizontal distances. During encounters where individuals approached too close to the vessel to use the reticule readings, a best possible estimation was made by eye. Where possible, photographs were taken using a DSLR camera to aid in species identification and to document the encounter.
