We describe scaling of morphological variables that influence total insulation in eight species marine mammals ranging average size from 35 to 30000 kg. also calculate heat loss and the partitioning through body surface appendages. For investigated, 0°C water is appreciably higher than predicted basal metabolic rates for small such as ringed seal. Rorquals, on other hand, will probably not need raise their keep warm. At rest, 10–30% production a resting animal lost flippers, fins flukes....
A 1680 km 2 coastal archipelago area in Norway around Sandøy (62°N 6°E), with a resident population of approximately 750 harbour seals was modelled geographic information system (GIS). The proportions different habitat types available to for foraging were estimated. Empirical data on levels activity and VHF radio-tracked used parameterise an energetics simulation model based activity, body size, composition. harbour-seal energy requirement simulated period from 20 June 31 August. diet the...
An increasing number of studies indicate that marine mammals and some seabirds are exposed to organotins. However, results from northern Arctic areas few. Here analysis tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT), triphenyltin (TPhT), diphenyltin (DPhT) monophenyltin (MPhT) in harbour porpoise (Phocoena phocoena), common seal (Phoca vitulina), ringed hispida) glaucous gull (Larus hyperboreus) Norwegian territory presented. Relatively high concentrations DBT, TBT MBT were observed...

Abstract Harbour porpoise (Phocoena phocoena) bycatch for Norwegian commercial gillnet fisheries from 2006 to 2018 was estimated using a traditional ratio estimator and generalized additive linear mixed models, with weight of fish landed number hauls as proxies fishing effort. Estimates were derived data collected contracted reference fleet small coastal vessels scaled up the whole landing statistics. Bycatch estimates exhibited large yearly variations, ranging 1151 6144 porpoises per year....
A bstract Between 1975 and 1998, 3,571 gray 630 harbor seal pups were tagged along the Norwegian coast, 259 (7%) 80 (13%) tags returned. Incidental mortality, mainly in bottom‐set nets, accounted for majority of deaths (79% 48% seals, respectively). Seals most vulnerable to incidental mortality fishing gear during first three months after birth, but high prevailed 8–10 mo. Gray seals dispersed more widely (mean distance: 120 km) than 69 km). Both species two tagging. The maximum distance...

Sperm whales (Physeter macrocephalus) are widely distributed in the Norwegian Sea and feeding aggregations occur. One of these is Bleik Canyon, close to shore Norway, where present study was performed. The used a whale safari company as platform from which conduct photo-identification male sperm whales. Data for this comprised total 3856 images 22 seasons (1987–2010) whale-watching tours. In total, 411 individuals were identified. This supports results previous studies Canyon confirms...
The male harbor seal (Phoca vitulina) produces broadband nonharmonic vocalizations underwater during the breeding season. In total, 120 from six colonies were analyzed to provide a description of acoustic structure and for presence geographic variation. complex may be described by how frequency bandwidth varies over time. An algorithm that identifies boundaries between noise signal digital spectrograms was developed in order extract contour. contours used as inputs multivariate analysis....

Abstract The northern Benguela ecosystem adjoining Namibia has undergone considerable changes in recent decades, with reductions and northwards shifts of key prey species that have had severe implications for marine top predator populations. We investigated how such environmental variability may impact foraging behaviour the Cape fur seal Arctocephalus pusillus pusillus, using satellite telemetry on animals northern, central southern Namibia. expected would reflect a gradient deteriorating...
Abstract Concentrations of mercury and selenium have been determined in liver kidney 92 harbor porpoises (Phocoena phocoena) caught along the Norwegian coast. The hepatic renal concentrations ranged from 0.26 to 9.9 0.15 3.5 μg g−1, respectively, whereas corresponding 0.74 14.2 0.60 8.6 respectively.

Introduction to Volume 8: Harbour seals in the North Atlantic and Baltic
The kelps Laminaria digitata and Saccharina latissima are typically sub-littoral species. It is therefore surprising to find large intertidal kelp beds dominated by these two species in the inner Porsangerfjord, North Norway. areas of nine ranged from 0.01 3 km2 covered a total area 8.3 km2. Both had prostrate growth form with short stipes, usually less than 10 cm long, independent length lamina. laminae L. S. measured 77.0 ± 35.2 99.4 41.0 (mean 1 SD), respectively. associations occurred...
