Humpback whale populations migrate extensively between winter breeding grounds and summer feeding grounds, however known links to remote Antarctic feeding grounds remain limited in many cases. New satellite tracks detail humpback whale migration pathways from Western Australia into the Southern Ocean. These highlight a focal feeding area during austral spring and early summer at the southern Kerguelen plateau, in a western boundary current where a sharp northward turn and retroflection of ocean… 
Round-trip migration and energy budget of a breeding female humpback whale in the Northeast Atlantic
In the northern hemisphere, humpback whales (Megaptera novaeangliae) typically migrate between summer/autumn feeding grounds at high latitudes, and specific winter/spring breeding grounds at low
Seasonal Distribution of the Fin Whale (Balaenoptera physalus) in Antarctic and Australian Waters Based on Passive Acoustics
The fin whale is listed as globally vulnerable, with ongoing threats to their population, yet little is known about the distribution and movements of the Southern Hemisphere sub-species, Balaenoptera
The Role of Environmental Drivers in Humpback Whale Distribution, Movement and Behavior: A Review
Humpback whales, Megaptera novaeangliae, are a highly migratory species exposed to a wide range of environmental factors during their lifetime. The spatial and temporal characteristics of such
Spatiotemporal Overlap of Baleen Whales and Krill Fisheries in the Western Antarctic Peninsula Region
In Antarctica, abundant consumers rely on Antarctic krill for food, but krill are also the subject of a commercial fishery. The fishery overlaps in time and space with the foraging areas of these
Otolith chemistry of Electrona antarctica suggests a potential population marker distinguishing the southern Kerguelen Plateau from the eastward‐flowing Antarctic Circumpolar Current
Large submarine plateaus impede the eastward flow of the deep‐reaching Antarctic Circumpolar Current (ACC), and at the southern Kerguelen Plateau (SKP), the ACC flow is steered north through the Fawn
Cetacean distribution in relation to oceanographic features at the Kerguelen Plateau
The Kerguelen Plateau in the south-eastern Indian Ocean is one of the most isolated and understudied regions on earth. As part of the Kerguelen Plateau Drifts project, Marine Mammal Observer (MMO)
Silver gull harassment of humpback whales in Exmouth Gulf, Western Australia
We share observations of silver gulls (Chroicocephalus novaehollandiae) harassing humpback whales (Megaptera novaeangliae) in Exmouth Gulf, Western Australia, between August and October in 2018 and
Marine Ecosystem Assessment for the Southern Ocean: Birds and Marine Mammals in a Changing Climate
The massive number of seabirds (penguins and procellariiformes) and marine mammals (cetaceans and pinnipeds) – referred to here as top predators – is one of the most iconic components of the
Dynamic Species Distribution Models in the Marine Realm: Predicting Year-Round Habitat Suitability of Baleen Whales in the Southern Ocean
Species distribution models (SDMs) relate species information to environmental conditions to predict potential species distributions. The majority of SDMs are static, relating species presence
Combining Regional Habitat Selection Models for Large-Scale Prediction: Circumpolar Habitat Selection of Southern Ocean Humpback Whales
It is proposed that ensemble approaches commonly used to combine different algorithms for a single region can be reframed, treating regional habitat selection models as the candidate models, and this approach can incorporate regional variation when fitting predictive models of animal habitat selection across large ranges.


Humpback whale migrations to Antarctic summer foraging grounds through the southwest Pacific Ocean
It is demonstrated that Antarctic foraging habitat is associated with the marginal ice zone, with key predictors of inferred foraging behaviour including distance from the ice edge, ice melt rate and variability in ice concentration two months prior to arrival.
Remote Antarctic feeding ground important for east Australian humpback whales
Determining the feeding grounds of Oceania’s whales may explain whether prey energetics or migration length are limiting factors to their recovery and will allow an understanding of future ecosystem changes in these whales.
Satellite tracking reveals novel migratory patterns and the importance of seamounts for endangered South Pacific humpback whales
Satellite telemetry suggests that seamounts represent an overlooked cryptic habitat for the humpback whale species, and the frequent use by humpback whales of such remote locations has important implications for conservation and management.
Isotopic Evidence of a Wide Spectrum of Feeding Strategies in Southern Hemisphere Humpback Whale Baleen Records
The first investigation of trophodynamics in Southern hemisphere humpback whales derived from baleen plates is presented, and the first estimates of balean plate elongation rates in the species are provided.
Southern Hemisphere humpback whales wintering off Central America: insights from water temperature into the longest mammalian migration
It is contended that while availability of suitable reproductive habitat in the wintering areas is important at the fine scale, water temperature influences whale distribution at the basin scale, a strategy that supports the energy conservation hypothesis as a reason for migration.
Long-range movement of humpback whales and their overlap with anthropogenic activity in the South Atlantic Ocean.
A spatial metric of overlap between whale habitat and models of cumulative human activities, including oil platforms, toxicants, and shipping is developed, which detected strong heterogeneity in movement behavior over time that is consistent with previous genetic evidence of multiple populations in the region.
Return movement of a humpback whale between the Antarctic Peninsula and American Samoa: a seasonal migration record
Humpback whales Megaptera novaeangliae are seasonal migrants that mate and calve at low latitudes and feed at mid- to high latitudes. Connections between most Southern Hemisphere breeding and feeding
Satellite-monitored movements of humpback whales Megaptera novaeangliae in the Southwest Atlantic Ocean
Southern Hemisphere humpback whales Megaptera novaeangliae migrate from wintering grounds in tropical latitudes to feeding areas in the Antarctic Ocean. It has been hypo- thesized that the population
Migratory interchange of humpback whales (Megaptera novaeangliae) among breeding grounds of Oceania and connections to Antarctic feeding areas based on genotype matching
Humpback whales (Megaptera novaeangliae) congregate to breed during the austral winter near tropical islands of the South Pacific (Oceania). It has long been assumed that humpback whales from Oceania
