title: Time-lapse video of McMurdo Ice Shelf surface melting and hydrology

description: During the Austral summer melt season of 2016-2017, an automatic camera was placed overlooking a surface lake feature on the McMurdo Ice Shelf. This camera created a time-lapse video (30 minute photograph time intervals) used to observe the filling and draining of the lake called Rift-Tip Lake located approximately 2 km from the McMurdo Ice Shelf ice front. The data was used in support of a field project to measure the flexural response of the McMurdo Ice Shelf (and ice shelves in general) to the filling and draining of supraglacial lakes.  The time-lapse video begins 16 November 2016 and ends 27 January 2017.

title: Antarctic MIZ, Pack Ice and Polynya Maps from Passive Microwave Satellite Data

description: Sea ice variability within the marginal ice zone (MIZ) and polynyas plays an important role for phytoplankton productivity and krill abundance. Therefore, mapping their spatial extent, seasonal and interannual variability is essential for understanding how current and future changes in these biologically active regions may impact the Antarctic marine ecosystem. Knowledge of the distribution of MIZ, consolidated pack ice and coastal polynyas to the total Antarctic sea ice cover may also help to shed light on the factors contributing towards recent expansion of the Antarctic ice cover in some regions and contraction in others. The long-term passive microwave 21 satellite data record provides the longest and most consistent record for assessing the proportion of the sea ice cover that is covered by each of these ice categories. This data set provides estimates of the MIZ, consolidated pack ice and polynyas from the NASA Team and Bootstrap sea ice concentration data sets, from 1979 to 2017.

title: Weddell Seal Molt Phenology Dataset

description: Animals can respond to dynamic environments through phenological plasticity of life history events; however, changes in one part of the annual cycle can diminish the success of subsequent life history events. Our aims were to determine the associations between reproduction and moult phenology across years and to quantify phenological plasticity across varying environmental conditions. We conducted demographic surveys of 4,252 flipper-tagged Weddell seals (Leptonychotes weddellii) in the Ross Sea, Antarctica during four austral summers. At each sighting, seals were assigned a moult code based on the visible presence of new fur, and the start date of each animal’s moult was back-calculated. This dataset contains data on pupping and moult timing for each animal used to address this question.

title: Weddell seal summer diving behavior

description: We examined the influence of sea ice break-out on seasonal diving patterns and diet of a top predator, the Weddell seal, to understand how phytoplankton blooms impact the vertical distribution of the food web. We captured female seals during the November and December lactation period and attached a LOTEK LAT1800 time-depth recorder (TDR) flipper tag with a 6 second sampling interval. Data were processed using the Iknos toolbox in MATLAB. Benthic dives (1% of all dives) were excluded from analyses because we were interested in quantifying seasonal changes in mid-water dives. Thus, we analyzed dives from 59 Weddell seals to characterize the diving depth and foraging effort of each seal across the austral summer over four years. We characterized seasonal changes in diving depth by calculating the mean across all seals of the maximum dive depth on each day for each seal. For more information see: Beltran, R. S. Bridging the gap between pupping and molting phenology: behavioral and ecological drivers in Weddell seals PhD thesis, University of Alaska Fairbanks, (2018).

title: Data from: Linking oceanographic conditions, migratory schedules and foraging behaviour during the non‐breeding season to reproductive performance in a long‐lived seabird

description: 1. Studies of the mechanisms underlying climate-induced population changes are critically needed to better understand and accurately predict population responses to climate change. Long-lived migratory species might be particularly vulnerable to climate change as they are constrained by different climate conditions and energetic requirements during the breeding and non-breeding seasons. Yet, most studies primarily focus on the breeding season of these species life cycle. Environmental conditions experienced in the non-breeding season may have downstream effects on the other stages of the annual life cycle. Not investigating such effects may potentially lead to erroneous inferences about population dynamics.
2. Combining demographic and tracking data collected between 2006 and 2013 at Kerguelen Island on a long-lived migratory seabird, the Black-Browed Albatross (Thalassarche melanophris), we investigated the links between sea surface temperature during the non-breeding season and behavioural and phenological traits (at-sea behaviour and migratory schedules) while accounting for different responses between birds of different sex and reproductive status (previously failed or successful breeders). We then explored whether variation in the foraging behaviour and timing of spring migration influenced subsequent reproductive performance.
3. Our results showed that foraging activity and migratory schedules varied by both sex and reproductive status suggesting different energetic requirements and constraints among individuals. Higher sea surface temperatures during late winter, assumed to reflect poor winter conditions, were associated with an earlier departure from the wintering grounds and an extended pre-breeding period. However, an earlier spring migration and an earlier return to Kerguelen grounds were associated with a lower breeding success.
4. Our results highlighted that behaviour during some periods of the non-breeding season, particularly towards the end of the wintering period and the pre-breeding period, had a significant effect on the subsequent reproductive success. Therefore caution needs to be given to all stages of the annual cycle when predicting the influence of climate on population dynamics.
