The current trajectory of king penguin (Aptenodytes patagonicus) chick numbers on Macquarie Island in relation to environmental conditions, 2007-2020

From 2007 to 2020, annual island-wide censuses of king penguin chicks were undertaken in the second week of August each year. This data was compared to environmental variables to understand what variables can be further explored to understand king penguin population changes. This data set contains chick count data, environmental parameters and R scripts used to investigate the current trajectory of the Macquarie Island king penguin population in relation to environmental variables. This data has been published in ICES Journal Of Marine Science (DOI to be provided).

Prey species found within Hooker Sea Lion scats

This dataset is a collection of presence-absence and %occurrence data of prey species found within scats of Hooker Sea Lions.  The data are presented in an excel spreadsheet.
Samples were collected from 54 scats.
From the abstract of the referenced paper:
Scats were collected from itinerant male Hooker's sea lions, Phocarctos hookeri, at Macquarie Island and the un-eroded faunal remains used to assess the diet. Un-eroded sagittal otoliths were used to identify teleost fish and to calculate fish size. Prey items included 14 taxa of teleost fish, cephalopods, gastropods, crustaceans and fur seals. Fish constituted the primary component of the diet. Prey species previously uncommon in the diet of seals and penguins around Macquarie Island were commonly eaten by Hooker's sea lions. The sub-Antarctic horse fish (Zanclorhynchus spinifer) and the Patagonian tooth fish (Dissostichus eleginoides) were the two most abundant species and occurred in 62.5% and 41.7% of all scats respectively. There were no age specific and individual differences in the diet of sea lions. Seasonal variances in diet were absent. Small plastic fragments (diameter ~ 1mm) were only found in association with Electrona subaspera otoliths. Some overlap was seen between the diet of itinerant male Hooker's sea lions and the commercial fisheries that currently occur around Macquarie Island.
This work was completed as part of ASAC project 2265 (ASAC_2265).

Spatial and temporal variation in the recruitment of benthic macroinvertebrates to artificial substrata

Metadata record for data from ASAC Project 1229
See the link below for public details on this project.
---- Public Summary from Project ----
This project will develop a method to monitor human impacts in the shallow marine environment of Antarctica.  Artificial substratum units, placed at polluted and unpolluted sites, will be recovered after a specific time interval and resident animal communities will be compared to identify the type and magnitude of impacts.
Data are community abundance data from artificial substrate units comprised of three nylon mesh pot scourers.  Taxa are identified to morphospecies. Substrates were deployed in nearshore waters of Casey Station.  Standard deployment was 1 year at 14m depth. Four main sites were used - Brown Bay, Newcombe Bay, O'Brien Bay and Browning Peninsula. Brown Bay is a known contaminated site.
Experiments were designed to investigate natural variation on spatial and temporal scales, habitat area and potential impacts of a contaminated site, Brown Bay.

Cetacean acoustic presence by species: TEMPO 2021 Sonobuoys

This data product contains acoustic presence and absences of cetacean species derived from the acoustic recordings made from sonobuoys deployed during the TEMPO voyage. The information in this data product is a spreadsheet containing one row for each sonobuoy deployed, and one column for each type of vocalisation that was detected. 
Acoustic data were converted into a spectrogram, and these were manually inspected (visually and aurally) by an expert familiar with many different types of commonly detected sounds from cetaceans. Presence and absence of all sounds of each type were given a single score for each sonobuoy.
Scores in each cell correspond to analyst's certainty of the presence of that species. Scores range from 0-4 indicating: 
4: Analyst certain that call type was present 
3: Analyst believed calls quite likely present (with reasonable certainty) 
2: Analyst thought calls could possibly have been present (but some uncertainty)
1: Analyst thought calls may have been present (but not very certain) 
0: Call type was not detected by analyst 
blank: Analyst did not inspect for this call type

Biology of Southern Ocean squid, ecological importance and potential commercial implications - a preliminary assessment

Metadata record for data from ASAC Project 1242
See the link below for public details on this project.
---- Public Summary from Project ----
This project will undertake preliminary assessment of Southern Ocean squid stocks.  Squids will be collected by jigging and light trapping off research vessels in the region of Macquarie Island and other selected locations where the opportunity arises.  Little is known about squid biology in the Pacific and Indian sectors of the Southern Ocean. This project will help to provide initial basic biological data on the squid species present.
18 squid we caught on-board the Aurora Australis  in November, 2001.
All were caught 200-300 kms south of Tasmania, by a hand-held squid jig, at latitude 47 South at a depth of 1m.
All samples caught on the 5/11/01 have the code QA/AA/80/01.   There was no code written for others caught on 3/11/01.
The fields in this dataset are:

Joseph Bonaparte Gulf 30 m bathymetry and derived Morphological Surfaces

Australia has established a network of 58 marine parks within Commonwealth waters covering a total of 3.3 million square kilometres, or 40 per cent of our exclusive economic zone (excluding Australian Antarctic Territory). These parks span a range of settings, from near coastal and shelf habitats to abyssal plains. Parks Australia manages the park network through management plans that came into effect for all parks on 1 July 2018. Geoscience Australia is contributing to their management by collating and interpreting existing environmental data, and through the collection of new marine data.  “Eco-narrative” documents are being developed for those parks, where sufficient information is available, delivering collations and interpretations of seafloor geomorphology, oceanography and ecology. Many of these interpretations rely on bathymetric grids and their derived products, including those in this data release.
Geoscience Australia has developed a new marine seafloor classification scheme, which uses the two-part seafloor mapping morphology approach of Dove et al (2016). This new scheme is semi-hierarchical and the first step divides the slope of the seafloor into three Morphological Surface categories (Plain, &lt;2°; Slope, 2-10°; Escarpment, &gt;10°). This classification was applied to the portion of the Beaman and Spinnocia (2018) 30 m grid within the marine park.

TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) - scientific voyage of the RV Investigator, 2021

This is a parent metadata entry for data collected during the 2021 TEMPO (Trends in Euphausiids off Mawson, Predators, and Oceanography) multidisciplinary voyage onboard the RV Investigator. The primary goal of TEMPO was to collect data to estimate krill biomass with a view to update the precautionary catch limit for krill in CCAMLR’s Division 58.4.2-East. The TEMPO voyage ran from February to March 2021. The survey consisted of six major acoustic line-transects to estimate krill biomass and to observe swarm behaviour across ecological and density gradients within the survey area south of 62°S between 55° and 80° E, and a single fine-scale krill box acoustic survey off the Mawson coast. The voyage successfully estimated mean areal biomass for the region. Along with acoustic survey, net sampling was also conducted, a swarm study system, deep-sea cameras and light traps were deployed, in addition to Krill Observational Moorings for Benthic Investigation (KOMBI) being deployed on the seafloor that will record the behaviour of krill throughout a full year to understand the dynamics and use of habitat in the surface layer as well as at seafloor. Comprehensive oceanographic (CTDS, XBTs ARGSO floats) and biological (plankton) sampling were also conducted to understand the habitat environment of krill and its predators. Predator observation was undertaken throughout the voyage to improve our understanding on the connectivity of the krill population, and overlap of distribution between krill and predators. The information gathered from the contributes to the design of tractable and sustainable long-term monitoring plan and to evaluate spatial management of the krill fishery.
