The hourglass dolphin Lagenorhynchus cruciger is the only regularly occurring small delphinid found south of the Antarctic Polar Front, yet little is known about its ecology and habitat use. This study uses 8 years (14 cruises) of standardized shipboard surveys during January–March (2003–2011) in southern Drake Passage near the South Shetland Islands to summarize the spatial distribution of hourglass dolphin sightings and quantify habitat use. Sighting data are linked to bathymetry (depth… 
Occurrence of hourglass dolphin (Lagenorhynchus cruciger) and habitat characteristics along the Patagonian Shelf and the Atlantic Ocean sector of the Southern Ocean
The present study contributes novel information on environmental measures associated with hourglass dolphin distribution in the South-West Atlantic and Southern Oceans and includes relatively high sighting clusters of this species in two highly productive and biodiverse areas.
First sighting of a live hourglass dolphin (Lagenorhynchus cruciger) in inland waters of southern Chile
Although the animal sighted is more likely a vagrant than a migrant to inland waters of southern Chile, it is even more uncertain what biological and/or physical properties were determinants in the movements of hourglass dolphin.
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)
A major autumn feeding ground for fin whales, southern fulmars and grey-headed albatrosses around the South Shetland Islands, Antarctica
Seabirds and marine mammals were recorded during an autumn expedition of icebreaking RV Polarstern between Punta Arenas and the South Shetland Islands, Antarctica in March/ April 2012 and it is suggested that the area deserves future biological studies, especially in autumn, and a special protection management.
Dynamic intra-seasonal habitat use by Antarctic fur seals suggests migratory hotspots near the Antarctic Peninsula
The hypothesis that fur seals display an increase in their at-sea abundance during mid- to late summer near the Antarctic Peninsula as they prepare to take up wintering grounds is tested and whether abundances of their potential prey, krill and myctophids, exhibit intra-seasonal variability is tested.
Spatial assessment of fin whale hotspots and their association with krill within an important Antarctic feeding and fishing ground
The GAM for mid-summer indicates that fin whale hotspots were positively related to SST, EKE and acoustically determined krill biomass, while the GAM for late-summers indicates the hotspots was negatively related to net-based krill abundance and positively relatedto acoustic krill BMI and EKE.
Spatio-temporal persistence of top predator hotspots near the Antarctic Peninsula
This work quantified species richness and abundance of seabirds and marine mammals in order to identify marine areas that are persistently attractive to top predators and developed a new hotspot variance metric based on the percentage of time that the species richness or abundance estimate at any one location is greater than 1 standard deviation above the long term means.
Can habitat characteristics shape vertebral morphology in dolphins? An example of two phylogenetically related species from southern South America
Although the Peale's dolphin and the hourglass dolphin are closely related phylogenetically, vertebral morphology is influenced by a diverse set of ecological and behavioral factors, reflecting a high degree of vertebral plasticity within the genus.
Modelling habitat use suggests static spatial exclusion zones are a non-optimal management tool for a highly mobile marine mammal
It appears that at the scale examined, most of the Hauraki Gulf is important for feeding and nursing rather than specific smaller regions being used for these functions, suggesting static management is not the optimal tool, as suggested here for a highly mobile species.
Evaluating the isotopic niche of beaked whales from the southwestern South Atlantic and Southern Oceans
This poster presents a probabilistic procedure for estimating the intensity of the volcanic activity in Tierra del Fuego during the period of June 21 to 29, 1997 and its results can be compared to those of previous seasons.


Oceanic circumpolar habitats of Antarctic krill
The unusual circumpolar distribution of krill reflects a balance between advection, migration, top–down and bottom–up processes, and the retention ofKrill in moderately productive oceanic habitats is a key factor in their high total production.
Geospatial variability of krill and top predators within an Antarctic submarine canyon system
This study test the hypothesis that spatial organization of krill and top predators co-vary according to fine-scale changes in bathymetry in the nearshore marine environment and highlights the multispecies approach for studying spatial ecology of top predators and krill.
Interannual spatial variability of krill (Euphausia superba) influences seabird foraging behavior near Elephant Island, Antarctica
It is concluded that annual patch dynamics of krill strongly influences the local abundance and distribution of seabirds, indicating that when krill is less abundant, its predators are less abundant and concentrated.
Current status of Odontocetes in the Antarctic
The current status of Antarctic Odontocetes – sperm whales Physeter catodon, killer whales Orcinus orca, long-finned pilot whales Globicephala melaena, hourglass dolphins Lagenorhynchus cruciger and
Interactions between Cetacean and Fisheries in the Southern Ocean
Soon after longlining on Patagonian toothfish started in the Southern Ocean in the second half of the 1980s, interactions of cetaceans with these fisheries became apparent and orcas and sperm whales took substantial number of fish from the line primarily during day light hours.
Cetacean sightings near South Georgia islands, South Atlantic Ocean
Data is presented on location, depth, group size, structure, and behavior for this geographical area of essential importance for cetacean conservation.
Cephalopods Occupy the Ecological Niche of Epipelagic Fish in the Antarctic Polar Frontal Zone.
A geographically distinct, Antarctic, open-ocean food chain which is of importance to air breathing predator species but where Antarctic krill, Euphausia superba, is absent is identified.
Ecological importance of the Southern Boundary of the Antarctic Circumpolar Current
The association of primary production, Krill, and whales with the Southern Boundary, suggests that it provides predictably productive foraging for many species, and is of critical importance to the function of the Southern Ocean ecosystem.
Spatial association between hotspots of baleen whales and demographic patterns of Antarctic krill Euphausia superba suggests size-dependent predation
It was found that baleen whales aggregated to krill hotspots that differed in size structure, and the correlation among different whale species and krill swarms of differing size presents an intriguing pattern that deserves further study.
