title: Processed Expendable Bathythermograph (XBT) casts collected during the 2022 Marion Relief Voyage on the SA Agulhas II Voyage 051, May 2022

description: SA Agulhas II Voyage 051
description: Here we present 49 processed Expendable Bathythermograph (XBT) casts collected in the South West Indian Ridge area and along the Crossroads Transect, between 18 May 2022 and 21 May 2022, during the 2022 Marion Relief Voyage on the SA Agulhas II Voyage 051. The South African component of the international South Atlantic Meridional Overturning Circulation project (SAMOC-SA) aims to characterise the time-mean and time-varying components of the SAMOC in the South Atlantic Ocean and monitor the variability of the main Southern Ocean frontal systems associated with the Antarctic Circumpolar Current (ACC), south of Africa. The Crossroads monitoring line, directly under the altimetry track N198, is sampled annually during the Marion Relief voyages, using a combination of Conductivity, Temperature, Depth (CTD) stations and XBT casts, where the XBT casts are done, at set intervals, between CTD stations to complement the CTD data.The 2022 Marion Relief Voyage 051 offered the 10th opportunity to conduct multi-disciplinary, ship-based oceanographic research on board the SA Agulhas II en route to, from, and around, the sub-Antarctic Prince Edward Islands (PEI’s).

The data is collected in *.bin format and then converted to *.txt files using the software. The *.txt files contain some metadata at the top of file, but not always fully completed by operators. The processed data has been edited, using the raw text data, where temperature spikes and XBT signal loss, at end of cast, were removed. Metadata containing cast details has been added to the top of the file for the 49 XBT casts

title: Processed underway Thermosalinograph (TSG) observations from the SA Agulhas II Voyage 041, December 2019

description: SA Agulhas II Voyage 041
description: A SeaBird SBE45 Thermosalinograph (TSG) is used to opportunistically collect underway near-surface temperature and conductivity measurements during research and monitoring cruises. Water is continuously pumped to the TSG from an intake located in the hull of the vessel, and the observations are continuously interfaced with navigational information. A temperature sensor close to the intake provides temperature measurements of the incoming water (T1). The temperature of the water inside the conductivity cell (T2) is used to accurately compute salinity (S) from the conductivity measurements (C). Here we present the 10-second resolution processed TSG data collected, between 12 December 2019 and 27 February 2020, during Voyage 041 on the SA Agulhas II.
description: The SeaBird SBE45 Thermosalinograph (TSG) is used on the SA Agulhas II for the collection of underway near-surface temperature and conductivity measurements. The underway seawater is obtained from a depth of 7m below the surface and pumped through the TSG. Data is collected using the most recent SeaBird (SBE) SeaSave software and processed using the most recent SBE Data Processing Software. The software was set to record data at 10 second intervals for the duration of the cruise, between 12 December 2019 and 27 February 2020. Data was collected in the southern part of the Benguela Current Large Marine Ecosystem (BCLME) region, on the west and south coasts of South Africa, in the eastern part of the South Atlantic Ocean, and in the Southern Ocean. Unreliable TSG measurements can result from a variety of problems encountered during the cruises, including insufficient water flow, extreme air bubbling during severly adverse weather conditions, debris trapped in the system, or a variety of electronic failures. Detailed visual inspection of the ship trajectory and TSG measurements, as well as comparisons with other concurrent and historical near-surface measurements, and expert knowledge of local conditions, were used to identify and remove all unreliable data.

The data is collected in *.bin format and then converted to *.txt files using software. The *.txt files contain some metadata at the top of file, but not always fully completed by operators. There is no editing done to the data in the acquisition software and so the bottom readings, where the XBT loses signal, have not been removed for the 58 XBT casts.

title: Marion Island Relief Voyage on the SA Agulhas II Voyage 045, May 2021

description: The Marion Island Relief Voyage was conducted on the SA Agulhas II Voyage 045 between 9 April and 12 May 2021. The 2021 Marion Relief Voyage 045 offered the 9th opportunity to conduct multi-disciplinary, ship-based oceanographic research on board the SA Agulhas II en-route to, from, and around, the sub-Antarctic Prince Edward Islands. Due to the world wide Covid-19 pandemic and the subsequent measures implemented by the South African government to contain the spread of the Covid-19 virus in South Africa, the main ship-based research objectives normally associated with the Marion relief voyage (as submitted through SANAP3 applications) were, like in 2020, once again curtailed. Thus, not all the approved NRF-funded SANAP projects could be accommodated. Similarly, annual ship-based research and monitoring conducted by the Oceans & Coasts Research Branch of DFFE was similarly substantially reduced. This was mainly due to the number of participants allowed to participate on the voyage and the limitation of only 8 ship-based scientists allocated berths on the voyage. The ship-based research was thus conducted as a joint multi-institutional, multidisciplinary effort with scientists, research technicians and students from the Department of Fisheries, Forestry and  the Environment: Oceans & Coasts Research (DFFE), the University of Cape Town (UCT), and the University of Pretoria (UP), all collaborating to achieve a number of research and monitoring project objectives.

title: Parkes observations for project PX600 semester 2020APRS_129

description: The Galactic Center (GC) is a key target for the radio component of Breakthrough Listen (BL) program. Offering the largest amount of stars in any given direction in the sky, the GC is widely cited as a location believed to harbour advanced civilizations, and it is also the most energetic region in the Milky Way. We aim to conduct BL-GC Survey with Parkes radio telescope for around 350 hours. We will cover the frequency range from 700 MHz to 4 GHz, utilizing the newly installed ultra-wideband receiver. Our team has already leveraged both standard and bespoke tools to construct a flexible software stack to search data for signals of interest. We will look for signals from extraterrestrial intelligence (ETI) by searching for both simple narrow-band signals and complex modulated signals. Along with that, as an ancillary science, we will also search for accelerated pulsars — likely orbiting a supermassive black hole at the centre of the Milky Way Galaxy. Data products produced during this program will also be publically available to engage larger pulsar community

title: CROCUS Dual Polarization Ceilometer Data at Northeastern Illinois University Rooftop

description: This dataset is from the Department of Energy Office of Science funded project, CROCUS Urban Integrated Field Laboratory (https://crocus-urban.org/).  The dual-polarization ceilometer (Vaisala CL61) is an autonomous lidar system operating at 910 nm wavelength, providing valuable measurements for understanding atmospheric boundary layer evolution, air quality, and cloud-aerosol interactions. The CL61 measures the backscattered signal intensity alternating between parallel- and cross-polarization signals. The unique depolarization measurement capability improves discrimination between different particle types, such as liquid droplets, ice crystals, and aerosols. The depolarization is highly dependent on the scatterer shape and orientation (spherical vs non-spherical particles), with the linear depolarization ratio providing a measure of dominant backscatter signal component from atmospheric particles at various heights, essentially allowing discrimination between liquid and solid particles. With its efficient optical system, CL61’s improved signal-to-noise ratio compared to traditional ceilometers allows studying detailed vertical profiles of aerosols and clouds up to 15 km height.Datasets are stored in a netCDF data format, and we we encourage users to make use of the associated toolkits available from Unidata (https://www.unidata.ucar.edu/software/netcdf/), Project Pythia (https://foundations.projectpythia.org/core/data-formats/netcdf-cf.html), and our “Instrument Cookbooks” (https://crocus-urban.github.io/instrument-cookbooks) for more information on how to process the metadata-rich datasets.
