  • An R data file containing a hierarchical switching state-space model of pygmy blue whale Argos-collected telemetry data using the bsam package (see Jonsen (2016). Joint estimation over multiple individuals improves behavioural state inference from animal movement data. Scientific Reports 6: 20625.) in R. The model estimated location states for each individual at regular 3-h time intervals, accounting for measurement error in the irregularly observed Argos surface locations; and estimated the behavioural state associated with each location. Satellite tags were deployed on pygmy blue whales located in the Bonney Upwelling region, SA, between 7 January and 16 March 2015. File can be opened in R (A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria. URL https://www.R-project.org/ ) using the code: readRDS('bw_3h_ssm.RDS')

  • This dataset contains estimates of krill swarm characteristics from statistical models based on underway acoustic observations along with underway and remote-sensed environmental data. Estimates of internal swarm density and depth across the study region (60-80 degrees E) are included for the time of the survey (Feb 2006). Estimates of February internal swarm density across the broader East Antarctic region (30-120 degrees E) are also included for the period 2001-2010.

  • This csv details the raw Argos locations generated from satellite tags attached to pygmy blue whales in order to describe their migratory movements through Australian waters as described in: Double MC, Andrews-Goff V, Jenner KCS, Jenner M-N, Laverick SM, et al. (2014) Migratory Movements of Pygmy Blue Whales (Balaenoptera musculus brevicauda) between Australia and Indonesia as Revealed by Satellite Telemetry. PLoS ONE 9(4): e93578. doi:10.1371/journal.pone.0093578 This csv includes the following data fields - ptt: the unique Argos identifier assigned to each satellite tag gmt: the date and time in gmt with the format 'yyyy-mm-dd hh:mm:ss' class: the Argos assigned location class (see paper for details) latitude longitude deploydate: deployment date and time in gmt for each tag with the format 'yyyy-mm-dd hh:mm:ss' filt: the outcome of the sdafilter (see paper for details) - either "removed" (location removed by the filter), "not" (location not removed) or "end_location" (location at the end of the track where the algorithm could not be applied)

  • Sixteen satellite tags were deployed on adult southern right whales. Six of these tags were deployed on adult southern right whales at the Auckland Islands (AI), New Zealand (50.5˚S 166.3˚E) between 24 July and 2 August 2009 and one tag was deployed on a sub-adult at Pirates Bay (PB), Tasmania (43.2˚S 147.9˚E) in October 2010. Nine tags were deployed on adult southern right whales at Head of the Bight (HOB), South Australia (31.5˚S 131.1˚E) on 6 and 7 September 2015. However, tag performance was highly variable. Three of the six tags deployed at the AI ceased transmitting before the individuals moved out of the winter aggregation area. No transmissions were received from a fourth tag until 39 days after deployment at which point the whale was south of Western Australia and although the tag transmitted for 22 days, there was insufficient data to interpolate a track suitable to be included in analyses. Of the nine tags deployed at HOB, three tags failed to transmit, and three tags ceased transmitting within six days. Migratory movements from coastal calving grounds were successfully obtained for six individuals (AI=2, PB =1, HOB = 3) and detailed in the publication: Migratory movements of Southern right whales (Eubalaena australis) from Australia and New Zealand. This file includes the following data fields - PTT: the unique Argos identifier assigned to each satellite tag Datetime: the date and time in gmt with the format 'yyyy-mm-dd hh:mm:ss' Longitude Latitude Quality: the Argos assigned location class (see paper for details) Location: deployment location
