Data for [The ISME Journal]: Microbial competition for iron determines its availability to the Ferrous Wheel

We dissect the spokes of the ferrous wheel associated with Fe demand by quantifying the uptake rates of heterotrophic bacteria and phytoplankton in the subantarctic Southern Ocean during summer and situate these findings within a seasonal context. To do so, we conducted bioassays in which the effects of light on Fe photochemistry and uptake physiology were studied by comparing light and dark incubations, and the effects of DOC supply and competition between phytoplankton and heterotrophic bacteria were examined by isolating bacteria from the larger members of the ferrous wheel by pre-incubation size fractionation.

Assessing the potential for “assisted gene flow" to enhance heat tolerance of multiple coral genera over three key phenotypic trails (RRAP_ECT2.1; Years 1+2)

This data was collected as part of the Reef Restoration and Adaptation Program (RRAP). Year 1 heat stress experiments were conducted on adult Acropora kenti (formerly A. tenuis), A. tersa (formerly A. hyacinthus &quot;neat&quot;), and Goniastrea retiformis as well as larvae and recruits generated from A. kenti and A. tersa adults (i.e., broodstock). Year 2 heat stress experiments were conducted on A. tersa larvae and recruit offspring groups. Year 1 and 2 experiments were collectively run between 01 November 2020 - 01 April 2022. The overall aim was to further our understanding about the potential benefits of using thermal history provenancing-informed selective breeding to generated offspring with enhanced resilience.

Mass coral bleaching and mortality events have increased in frequency over the last 30 years. Genetic interventions like assisted gene flow may speed up adaptation in reefs with less heat-tolerant corals by increasing the frequency of heat tolerance-associated genetic variants. To investigate, we generated reproductive crosses of corals from reefs along a thermal gradient on the Great Barrier Reef, comparing fitness traits in intra-region and inter-region offspring from three species (Acropora kenti, A. hyacinthus, and Goniastrea retiformis). Juveniles were inoculated with three heat-tolerant symbionts: Durusdinium trenchii, a heat-evolved Cladocopium goreaui strain, and &ldquo;wild&rdquo; symbionts from northern reef sediments. Survival, growth, colour change, and effective quantum yield of photosystem II (YII) were measured across larvae, juveniles, and adults at elevated and ambient temperatures. Results showed higher survival in some inter-region crosses compared to intra-region crosses from central reefs in larvae and juvenile corals, though enhancement varied by species. Heat-tolerant parents did not always produce heat-tolerant offspring and larval heat tolerance did not consistently persist to juveniles. Parent genetic background influenced survival more than innoculated symbiont. These findings underscore the complexity of heat tolerance acquisition in early coral life stages.

IMOS - Ships of Opportunity - Expendable Bathythermographs - XBT real-time data

The IMOS Ships of Opportunity Expendable Bathythermographs Sub-Facility was formerly known as the Underway Expendable Bathythermographs (XBT), a research and data collection project working within the former IMOS Ship of Opportunity Multi-Disciplinary Underway Network Sub-Facility.

XBT real-time data is available through the IMOS portal. Data is acquired by technicians who ride the ships of opportunity in order to perform high density sampling along well established transit lines. The data acquisition system used is the Quoll developed by Turo Technology. Data collected and is stored in netcdf files, with real-time data messages (JJVV bathy messages) created on the ship and sent to shore by iridium sbd. This is inserted onto the GTS by our colleagues at the Australian Bureau of Meteorology. The full resolution data is collected from the ship and returned for processing to scientists at CSIRO in Hobart. It undergoes a full scientific QC process which identifies both bad data and oceanic features such as eddies, fronts and temperature inversions. Finally, the data is distributed to the GTSPP global data acquisition centre in Washington DC where it is made freely available to all. This SOOP dataset covers waters around Australia and across to New Zealand.

Comparison of predation on Centrostephanus rodgersii inside/outside marine reserves in eastern Tasmania

The predators of Centrostephanus rodgersii, were identified using remote video monitoring. Experiments were performed in two eastern Tasmanian regions, the Maria Island Marine Reserve (MIMR, 42° 35.26'S, 148° 3.03'E) and the Crayfish Point Research Reserve (CPRR, 42° 57.37'S, 147° 21.30'E). The impact of fishing on these predators, and ultimately on C. rodgersii, was examined by comparing survival of C. rodgersii on reefs inside no-take Marine Protected Areas (MPAs) (high predator biomass) relative to fished reefs (low predator biomass). The size-specific nature of predation interactions was examined in context of size-selective fishing pressures within the sea urchin's extended range.

IMOS - Satellite Remote Sensing - NOAA20 - 01 day - Chlorophyll-a concentration (GSM model)

The NOAA20 satellite platform carries a VIIRS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water. 

There are multiple retrieval algorithms for estimating Chl-a. These data use the Garver-Siegel-Maritorena (GSM) method implemented in the SeaDAS processing software l2gen and described in “Chapter 11, and references therein, of IOCCG Report 5, 2006, (http://ioccg.org/wp-content/uploads/2015/10/ioccg-report-05.pdf).

Photogrammetric video tracking of whale movements during the ENRICH voyage (IN2019_V01)

This record describes photogrammetric video tracking data collected during the Marine National Facility (MNF) RV Investigator voyage IN2019_V01, ENRICH (Euphausiids and Nutrient Recycling in Cetacean Hotspots), conducted in the Southern Ocean between 19 January and 5 March 2019. The voyage investigated the availability of Antarctic krill to large predators and their role in biogeochemical nutrient recycling. A digital photogrammetric video tracking system was used to determine the range and bearing of surfacing cetaceans relative to the research vessel, enabling precise measurements of surface locations and fine-scale movement. Video tracking was conducted on 24 occasions for a total of approximately 18 hours, primarily targeting Antarctic blue whales, with additional observations of fin whales. Focal follows were terminated when sea ice or the presence of multiple animals prevented reliable identification of the focal individual. The dataset provides baseline information on cetacean surface behaviour and movement and supports investigations of the relationships among whale behaviour, movement patterns, and vocal activity in the Southern Ocean.

IMOS - Satellite Remote Sensing - NOAA20 - 01 day - Diffuse attenuation coefficient (k490)

The NOAA20 satellite platform carries a VIIRS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the diffuse attenuation coefficient (Kd) at 490nm wavelength which provides information on how light is attenuated in the water column. It is defined as the scaling length of the exponential decrease of the downwelling irradiance, and has units (m^-1). The VIIRS K490 product estimates Kd at 490nm wavelength, using a semi-empirical model based on the ratio of water leaving radiances at 490nm and 555nm. The algorithm is described at https://oceancolor.gsfc.nasa.gov/atbd/kd/.

Redmap (Western Australia) - Sightings of Shark and Ray Species

Redmap is a primarily a website that invites the community to spot, log and map marine species that are uncommon in their region, or along particular parts of their coast. The information collected is mapped and displayed on the site, demonstrating, in time, how species distributions may be changing.

Sightings are divided into two categories – those with a photo that can be ‘verified’ by a marine biologist, and sightings without photos that we call community sightings (anecdotal). All the information collected, with and without photos, is mapped and will be used in the following years to map out a ‘story’ of changes occurring in our marine environment.

The main data collected includes the species sighted (normally selected from a list comprising preselected species of interest), the location, date/time and activity being undertaken.  Other optional information gathered include biological data such as sex, size and weight and environmental data such as water depth and temperature and habitat.

This record is associated with live data (and will subsequently change over time) and spatial elements have reduced accuracy.  It is also subject to a three year embargo (ie. does not contain data less than three years old).  If you wish to discuss obtaining a citable, static dataset, that is current and/or contains accurate spatial elements, please see Point of Contact.

Seamap Australia NBHL collated habitat datasets - superseded datasets for archival purposes

The Seamap Australia National Benthic Habitat Layer (NBHL) is a nationally synthesised database of seafloor habitat data, classified according to the Seamap Australia National Benthic Habitat Classification Scheme (https://vocabs.ardc.edu.au/viewById/129).

In generating the Seamap Australia NBHL, datasets from data providers around Australia are collated and centrally hosted by IMAS (UTAS). Through time, some datasets become superseded by newer, more accurate data for the same region (improved data collection or processing methodology). This record aggregates all habitat datasets that have been collated as part of the Seamap Australia project, but are no longer considered the most accurate/up to date habitat for a particular region and have been superseded by another product.

The parent record for the Seamap Australia NBHL provides an aggregation point for all "current" habitat datasets: https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a

Assessing the influence of ocean alkalinity enhancement on a coastal phytoplankton community - manuscript data

The effect of ocean alkalinity enhancement on a coastal phytoplankton community was assessed via a microcosm experiment. The effect of alkalinity enhancement in two scenarios (i) when enclosed seawater was in equilibrium with atmospheric CO2 and (ii) when enclosed seawater was not in equilibrium with atmospheric CO2 were explored. Alkalinity was increased by ~497 umol/kg in these two treatments and plankton communities, carbonate chemistry, dissolved inorganic nutrients, particulate matter and chlorophyll a dynamics monitored over a 22 day period where a spring bloom occurred.

IMOS - Animal Tracking Facility - Acoustic Receiver Locations

The Acoustic Telemetry Sub-Facility of the IMOS Animal Tracking Facility (formerly known as the Australian Animal Tracking And Monitoring System (AATAMS)) supports a large network of strategically located acoustic receivers in waters around Australia to detect and track tagged animals. The use of a network of acoustic receivers provides a powerful tool for observing animal movements in Australian coastal and continental shelf ecosystems. An array or network consists of a series of acoustic receivers that are strategically deployed on the sea floor for 1 to 10 years (depending on receiver type and battery life) with the ability to download data from the receivers as often as required. Acoustic Telemetry makes it possible for animals to be monitored over scales of hundreds of metres to thousands of kilometres, informing habitat use, home range size, effectiveness of marine protected areas, refinement of stock assessment and migratory patterns. The Animal Tracking Facility and the Australian Ocean Data Network (AODN) have worked together to create a readily accessible Database. The data search page displays all existing and historical acoustic receiver locations that have contributed to the national telemetry network maintained by the Animal Tracking Facility and collaborators. Only the most recent receiver deployment for each acoustic receiver station is displayed in this dataset collection on the AODN Portal. In this dataset collection, active deployments consist of all deployments deployed and not recovered within a 24 months timeframe. Unrecovered receiver deployments older than 24 months are considered as inactive deployments. The data page is hosted by the AODN and is updated by the Animal Tracking Facility team.
