SR3 2018 Particulate Iron Data

The following dataset contains particulate iron data collected during the 2018 occupation of the CLIVAR SR03 (GEOTRACES GS01) transect south of Tasmania, Australia. This data is used ancillary to measurements of dissolved iron in the same transect for a manuscript in preparation by Traill et al. (2023). 
While modelling efforts have furthered our understanding of marine iron biogeochemistry and its influence on carbon sequestration, observations of dissolved iron (dFe) and its relationship to physical, chemical and biological processes in the ocean are needed to both validate and inform model parameterisation. Where iron comes from, how it is transported and recycled, and where iron removal takes place, are critical mechanisms that need to be understood to assess the relationship between iron availability and primary production. To this end, hydrographic and trace metal observations across the GO-SHIP section SR3, south of Tasmania, Australia, have been analysed in tandem with the novel application of an optimum multiparameter analysis. From the trace-metal distribution south of Australia, key differences in the drivers of dFe between oceanographic zones of the Southern Ocean were identified. In the subtropical zone, the source of dFe was constrained by waters advected off the continental shelf, and by remineralization in recirculated modified mode and intermediate water masses of the Tasman Outflow. In the subantarctic zone, the seasonal replenishment of dFe in Antarctic surface and mode waters appears to be sustained by iron recycling in the underlying mode and intermediate waters. In the southern zone, the dFe distribution is likely driven by dissolution and scavenging by high concentrations of particles along the Antarctic continental shelf and slope, entrained in high salinity shelf water. This approach to trace metal analysis may prove useful in future transects for identifying key mechanisms driving marine dissolved trace metal distributions.

Satellite Remote Sensing - Satellite Contributed Ocean Colour - MODIS - Aqua Chlorophyll Concentration in the Southern Ocean: Weekly, Johnson et al 2013

The Aqua and Orbview satellites carry a MODIS and SeaWIFS sensors (respectively) 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 and aggregating the data over time. This data set is a reprocessed copy of 9km monthly and 8-day versions produced globally by NASA, adjusted for the Southern Ocean south of latitude 30S. The full methodology is described in Johnson, R., Strutton, P.G., Wright, S.W., McMinn, A., Meiners, K.M., 2013. Three improved satellite chlorophyll algorithms for the Southern Ocean. Journal of Geophysical Research: Oceans. doi: 10.1002/jgrc.20270. It is expected that the data set will be periodically updated with contemporary data as it becomes available.
There are four sub-streams within this data set. A monthly and an 8-day series for MODIS/Aqua and similarly for SeaWIFS. Note that SeaWIFS ceased operation in late 2010 so there will be no further SeaWIFS data. 
The data represented by this record is weekly data for MODIS/Aqua.

Small Pelagic Finfish Sustainability

Pilchards have traditionally been the largest volume finfish fishery in WA. Commercial fishers use purse seine nets to catch small pelagic finfish species off the south, lower west and mid-west WA coast.
Pilchards (Sardinops sagax) are the main species on the south coast, with the tropical species sardinella, also called scaly mackerel, (Sardinella lemuru) co-dominant on the west coast and dominant in the mid-west fishery. The sardinella are managed as part of an ecosystem where they are an important food for seabirds, especially at the Abrolhos Islands.
The South Coast Purse Seine Fishery has three management zones: Albany, Bremer Bay and Esperance. A proposed management plan for the West Coast Pilchard Fishery is likely to divide it into lower west and mid-west zones.
Management is by annual quotas and limitations on number of licenses. Monitoring of the commercial catches in each management zone and periodic biomass surveys are required to assess the status of the stocks so as to provide accurate advice for management. A Total Allowable Catch (TAC) is set for each zone following stock assessment.
The fish populations are still recovering after the serious pilchard herpes virus epidemic in 1998/99. A five-year FRDC project includes spawning biomass surveys studying the pilchards' recovery.
The project will:
* Monitor commercial catches and fishing effort in each region.
* Collect biological data and data for completing model-based stock assessment.
* Provide timely and informed scientific advice on relevant fish stocks and fishing impacts to the Commercial Program Manager and stakeholders.
* Provide expert scientific input to the Department of Fisheries's policy development process.
* Develop and maintain an adequate fishery database on the purse seine fisheries to enable the status of the stocks involved to be assessed annually.
* Provide an overview annual report on the status of the purse seine fisheries that target small pelagic fish.

Benthic processes in the intertidal mudflats of the Fly River estuary, Papua New Guinea

Three types of mudbanks were studied: a physically dominated, high sedimentation regime (1 station), a biologically dominated, low-to-moderate sedimentation regime (1 station); and a 'transitional' regime (2 stations).Bacterial C production was estimated from rates of protein (3H-leucine incorporation) and DNA (3H-thymidine incorportion) synthesis.Levels of particulate organic C, total N, total P in the sediments and dissolved organic (DOCChlorophyll a and phaeopigments were estimated.Meiofauna (Nematoda, Harpacticoid Copepoda, Foraminifera, others); macroinfauna (Polychaeta, Crustacea, Oligochaeta, others); and macroparticulate plant detritus (&gt; or = to 0.5mm) were measured.
 To assess the role of intertidal mudbanks in the storage, utilisation and export of nutirents from the Fly River delta to the adjacent Gulf of Papua.
 This research project was a component of a larger project to determine the influence of freshwater and detrital export from the Fly River system on adjacent pelagic and benthic systems in the Gulf of Papua.

2020 Aerial survey data of southern right whales (Eubalaena australis) off southern Australia

Annual aerial surveys of southern right whales have been conducted off the southern Australian coast, between Cape Leeuwin (W.A.) and Ceduna (S.A.) over a 28 year period between 1993 and 2020, to monitor the recovery of this species following commercial whaling. We conducted an aerial survey of southern right whales between the 20th and 24th August 2020, to continue these annual series of surveys and inform the long-term population trend. The comparable count for the 2020 survey utilised the maximum count for each leg and incorporated a correction for the unsurveyed area between Head of the Bight to Ceduna due to the inability to cover whole survey as a result of COVID-19 restrictions between State borders. This resulted in 384 individuals, consisting of 156 cows accompanied by calves of the year and 72 unaccompanied adults. Of these, 126 images of individual whales have been selected for photo-identification matching. This is a significant decrease in overall sightings that has not been observed for over 13 years when compared to long term trend data for the population; last seen in 2007 (N = 286 individuals). The subsequent population estimate for the Australian ‘western’ subpopulation is 2,585 whales, which is also a significant decrease in estimated population size from 3,164 in 2019 to 2,585 in 2020. The extremely low number of unaccompanied adults (N = 68) had the greatest impact on the overall number of sightings in 2020, and is the lowest number sighted since 1993 (N = 47). Previous surveys in 2007 and 2015 have been noted as years of low whale counts that had been deemed anomalous years, although the low numbers from this survey questions this and may suggest the 3-year female breeding cycle is becoming more unpredictable. Considerable inter-annual variation in whale numbers, and cycles in population growth, makes it difficult to detect consistent and reliable changes in abundance from one year to the next, or even over longer periods of time. This severely inhibits our ability to identify immediate threats to the population and strongly supports continued annual population surveys.

WAMSI Node 3.1.1b and 3.2.2 - Ecosystem Effects of Fishing: finescale coral reef fish surveys Ningaloo Reef - Mandu reference

From 2006 to 2007 at northern Ningaloo Reef, stereo Baited Remote Underwater Video (stereo-BRUVs) and stereo Diver Operated Video (stereo-DOVs) were used to measure fish assemblages across shallow coral reef lagoon habitats. Four areas were identified including Osprey and Mandu Sanctuary, and Osprey and Mandu Reference Areas which were studied with stereo-BRUV and stereo DOV transects, during two successive summer and winter periods. Each time, six stereo BRUVs and 5 stereo-DOV transects were collected from within 6 coral reef lagoon habitats at 2 well established sanctuary zones and adjacent areas.  The video footage was used to create the raw abundance and length data of different fish species.

Fast Repetition Rate Fluorometry (FRRF) data collected on the RV L'Astrolabe from 26/02/2005 to 03/03/2005 (Dumont d'Urville - Hobart)

These data were collected on the RV L'Astrolabe (platform code: FHZI) from 26/02/2005 to 03/03/2005 on a trip from Dumont D'Urville to Hobart.
Maximum photochemical efficiency of photosystem II (PSII), also called maximum quantum yield of PSII (Fv/Fm), has become one of the most widely utilized fluorescence parameters in phytoplankton research. It represents the potential photochemical efficiency, which is the probability that the light energy captured by the photosynthetic apparatus is being utilized as photochemistry. Fv/Fm has been shown to have an instant response to variations in physical and chemical properties and is interpreted as a diagnostic of the overall health or competence of phytoplankton. Together with the absorption cross section area of PSII and chlorophyll concentration, it can be used to measure primary production (Cheah et al. 2011, Deep Sea Research).
Seawater from 3 m depth was supplied continuously from the ship’s clean seawater line. FRR fluorescence yields were measured continuously at 1 minute intervals in dark-adapted state (! 15 minutes dark-adaptation) using a flash sequence consisting of a series of 100 subsaturation flashlets (1.1 μs flash duration and 2.8 μs interflash period) and a series of 20 relaxation flashlets (1.1 μs flash duration and 51.6 μs interflash period).

Water circulation around reefs in a region of high reef density on the Great Barrier Reef

From January to March 1994, vector-averaging Aanderaa and InterOcean S4 current meters were deployed at four locations along a cross-shelf transect between Bowden Reef and Darley Reef and a fifth current meter was deployed in a gully through the reef crest at Darley Reef. A tide gauge was also deployed in shallow waters at Old Reef. CTD data were collected at each mooring on deployment and on recovery. All current meters and the tide gauge recorded 30 minute averaged data.A series of models were used to calculate currents, predict the trajectories of water born-tracers and calculate tidally-predicted currents. Results from the field and the model were visualised using IBM's Data Explorer.
 This research was initiated to collect field data to enable modelling of the circulation of water around reefs in a region of high reef density.

Water current readings at the 'Green' mooring in the North West of Jervis Bay: 06/12/88 - 11/01/89

A current meter mooring was deployed in the NW section of Jervis Bay (35.03S, 150.7E) between 6/12/88 and 11/1/89. This mooring held two water current metres: an S4 Interocean current meter at a depth of 5.5m, and an Aanderaa (RCM7) meter at a depth of 9.5m. 
Each of these current meters provided two datasets. In the first, the meter integrates the signals over 2 minutes every 10 minutes, providing 10 min sample readings. The second decimated the samples using a running mean to provide hourly intervals. 
The data provided in the datasets includes the eastern and northern tidal components, speed, direction and temperature. The datasets providing the 10 minute sample values also give depth and salinity readings. 
The Aanderaa meter at 9.5m should have provided eastern and northern tidal components over the duration of the sampling period, however the compass jammed and did not work at all. Water speed was recorded but gives no indication of the direction of water movement.
Unfortunately one dataset is missing from this collection: The decimated hourly intervals for the meter at 9.5m have not been located, and are therefore not provided in this record

WAMSI Node 6.1 - Offshore and coastal engineering and the effects of climate change - Sea level / storm surge model (future)

Within WAMSI Node 6.1 the probabilities of extreme sea level for the present climate have been estimated using a 60 year hindcast of sea levels.  
This modelled sea level dataset has been used to map current recurrence intervals around the coastline of southwest Australia. Future changes in extreme sea levels throughout the 21st century have been estimated by increasing the current recurrence intervals by a low (18 cm) and upper (79 cm) sea-level rise projection. Results have shown that the predicted rise in sea level over the 21st century has the potential to significantly reduce current average recurrence intervals around southwest Australia and that the increase in exceedence frequency varies significantly around the coast. These estimates could increase further with enhanced storminess and this will be investigated in the next stage of the study.
