The humpback whale population of New Caledonia appears to display a novel migratory pattern characterized by multiple directions, long paths and frequent pauses over seamounts other shallow geographical features. Using satellite-monitored radio tags, we tracked 34 whales for between 5 110 days, travelling 270 8540 km on their southward migration from breeding ground in southern Caledonia. Mean speed was 3.53±2.22 h −1 , while movements within the averaged 2.01±1.63 . tag data demonstrate...
Humpback whales wintering in the entire West Indies chain are widely treated as comprising a single breeding population. However, most areas outside of Silver Bank and Samana Bay, Dominican Republic, poorly sporadically studied. Data is presented on timing movement patterns 262 from southeastern Caribbean, extending Antigua north to Trinidad Tobago south. Whales area were re-sighted all major North Atlantic feeding grounds. 43 individuals areas, animals eastern grounds significantly...
North Atlantic humpback whales (Megaptera novaeangliae (Borowski, 1781)) migrate from high-latitude summer feeding grounds to low-latitude winter breeding along the Antillean Island chain. In winters and springs of 2008 through 2012, satellite tags were deployed on Silver Bank (Dominican Republic) in Guadeloupe (French West Indies) areas. Whales monitored, average, for 26 days (range = 4–90 days). Some animals remained near their tagging location multiple before beginning northerly...
Southern Hemisphere humpback whales (Megaptera novaeangliae) generally undertake annual migrations from polar summer feeding grounds to winter calving and nursery in subtropical tropical coastal waters. Evidence for such arises seasonality of historic whaling catches by latitude, Discovery natural mark returns, results satellite tagging studies. Feeding is believed be limited the southern region, where Antarctic krill (Euphausia superba) has been identified as primary prey item....
The North Pacific right whale ( Eubalaena japonica ) was heavily exploited by both nineteenth century whaling and recent (1960s) illegal Soviet catches. Today, the species remains extremely rare especially in eastern Pacific. Here, we use photographic genotype data to calculate first mark–recapture estimates of abundance for whales Bering Sea Aleutian Islands. were very similar: = 31 (95% CL 23–54), genotyping 28 24–42).

Manned aerial surveys have been used successfully for decades to collect data infer cetacean distribution, density (number of whales/km 2 ), and abundance. Unmanned aircraft systems (UAS) potential augment or replace some manned cetaceans. We conducted a three-way comparison among visual observations made by marine mammal observers aboard Turbo Commander aircraft; imagery autonomously collected Nikon D810 camera system mounted belly port on the Commander; similar remotely controlled...
Around 176500 whales were killed in the sub-Antarctic waters off South Georgia (South Atlantic) between 1904 and 1965. In recent decades, have once again become summer visitors, with southern right whale (SRW) most commonly reported species until 2011. Here, we assess distribution, temporal pattern, health status likely prey of SRWs these waters, combining observations from a summertime vessel-based expedition to Georgia, stable isotope data collected putative sightings reports collated by...
Humpback whales (Megaptera novaeangliae) are showing strong recovery from commercial whaling in the western South Atlantic. In this region, humpback migrate annually their winter breeding grounds off coast of Brazil to summer feeding near Polar Front, an area that includes waters Georgia and Sandwich Islands (SGSSI). This latter region a Marine Protected Area (MPA), which has been developed ensure sustainable management fisheries, protection foraging predators. To date, measures within MPA...
In species that aggregate for reproduction, the social and fitness costs of movement between groups frequently lead to restricted exchange breeding areas. We report on four individual humpback whales identified in both Cape Verde Islands Guadeloupe; locations separated by an ocean basin >4000 km. This rate is rarely encountered such geographically discrete Two individuals returned area where they were originally identified. contrast, no from resighted much larger sample Dominican...
As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation management. This is particularly true in with high dispersal capacity, such as migratory whales, where patterns could change rapidly. Here we build on a previous long-term, large-scale collaboration southern right whales (Eubalaena australis) combine new (nnew) published (npub) mitochondrial (mtDNA) microsatellite genetic data all major...

Manned aerial surveys are routinely used to assess cetacean distribution and density, often over large geographic areas. Unmanned aircraft systems (UAS) have been identified as a technology that could augment or replace manned for cetaceans. To understand what research questions involving density can be addressed using UAS in the Arctic, we conducted paired cetaceans near Utqiaġvik (Barrow), Alaska. We present methods operational results from project, challenges encountered during field...
Assessing environmental changes in Southern Ocean ecosystems is difficult due to its remoteness and data sparsity. Monitoring marine predators that respond rapidly variation may enable us track anthropogenic effects on ecosystems. Yet, many long-term datasets of are incomplete because they spatially constrained and/or already modified by industrial fishing whaling the latter half 20th century. Here, we assess contemporary offshore distribution a wide-ranging predator, southern right whale...

Abstract Humpback whales ( Megaptera novaeangliae ) are a cosmopolitan species and perform long annual migrations between low-latitude breeding areas high-latitude feeding areas. Their populations appear to be spatially genetically segregated due long-term, maternally inherited fidelity natal In the Southern Hemisphere, some humpback whale mix in Ocean waters summer, but very little movement Pacific Atlantic has been identified date, suggesting these constituted an oceanic boundary distinct...

Systematic surveys estimating whale abundance in Ocean are not yet available. Records sightings have been collected a variety organisations over past few decades, incorporating both opportunistic data and dedicated survey data.

An essential component of risk assessment is identification whether individuals will be exposed to a risk. This requires information on the proportion population exposed, for how long, and during what activity (i.e., feeding, migrating, breeding). Using satellite telemetry data humpback blue whales feeding migratory regions in Antarctica, California, Bering Sea, we modeled potential exposure an acoustic disturbance. Foraging transit along tracks were identified time spent foraging each...
