Such large-scale irregularities on the ocean floor, even at great depths, impose a significant blocking action because they deflect deep-ocean currents upwards, the flow bringing with it nutrient-rich bottom sediments to promote phytoplankton and zooplankton blooms near the surface. Such areas of upwelling in turn strongly influence the foraging distributions of albatrosses and other seabirds. Prominent features of this kind in the Southern Ocean include the South Sandwich Ridge east of Drake Passage between the Antarctic continent and South America, the Kerguelen Plateau in the Indian Ocean sector, and the Campbell Plateau and the associated Macquarie Ridge extending south of New Zealand.

As in other studies of the day, it seemed much was found dead rather than killed. It was also speculated that albatrosses might attend sperm whales (which also feed mainly on squid) to scavenge vomit or the leavings of their kills. However, it was also widely recognised that weight estimates might be heavily biased in favour of larger prey because the bigger the squid the bigger the beak, and these therefore last longer in the albatross gut.
