description: Processed Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA) data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 223, February 2016
description: This is processed Dissolved Inorganic Carbon (DIC) and Total Alkalinity (TA) data from the Integrated Ecosystem Programme cruise in the Southern Benguela (IEP-SB). The cruise took place from 9 to 14 February 2016 aboard the RV Algoa. A total of 33 stations were occupied along three transect lines on the west coast of South Africa. Ten Conductivity, Temperature, Depth (CTD) stations were occupied along the Kleinsee Monitoring Line (KML) of Kleinsee, ten along the Namaqua Monitoring Line (NML) of Namaqua, eleven stations along the St Helena Bay Monitoring Line (SHBML) and two separate stations in the low oxygen zone in St Helena Bay. Discrete water samples were collected in 500ml Certified Reference Materials (CRM) bottles from Niskin bottles and spiked with 0,02% of Mercuric chloride before being stored in the dark at room temperature for later analysis in the laboratory ashore using a Versatile INstrument for the Determination of Total inorganic carbon and titration Alkalinity (VINDTA). The purpose of the observations was to characterise ocean acidification conditions, monitor long-term changes with respect to ocean acidification, to detect long-term anthropogenically-driven changes in carbon chemistry and to identify spatial and temporal variations in the carbon chemistry on the west coast of South Africa.
description: Dissolved Inorganic Carbon (DIC) samples were drawn from Niskin bottles into either 500ml borosilicate glass flasks using silicone tubing according to the procedure outlined in the Guide to Best Practices for Ocean CO2 Measurements (www.ncei.noaa.gov/access/ocean-carbon-acidification-data-system/oceans/Handbook_2007.html). Bottles were rinsed three times and filled from the bottom. Trapped air bubbles were dislodged while overflowing by at least one-half volume. The sample tube was pinched off and withdrawn to create a headspace. 0,02% of saturated HgCl2 solution was added before bottles were sealed with glass stoppers. The Versatile INstrument for the Determination of Total Alkalinity (VINDTA 3C) system from Marianda in Germany was used to measure the DIC of seawater. The accuracy of the DIC measurement was determined by Certified Reference Materials (CRMs) supplied by Dr. Andrew Dickson of Scripps Institution of Oceanography. The CRM-certified DIC and AT values for batch 158 used were 2043.54µmol/kg and 2226.55µmol/kg respectively. Each day run started with 4-6 junks, 2-4 test samples, a CRM, followed by 15 samples and a CRM. CRMs and samples were equilibrated to 25°C before analysis.

title: Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 258, February 2019

description: This Integrated Ecosystem Programme: Southern Benguela (IEP:SB) cruise was conducted on the Algoa Voyage 258 in February 2019. This is a long-term monitoring line conducted off the coast of Kleinsee, Namaqualand, Elands/St Helena Bay and Scarborough on the west coast of South Africa. The IEP:SB in 2013 consolidated a long-term, multi-decadal time-series (from 1951 onward) of information for this important region and has continued monitoring in the form of the IEP:SB. The programme is a multi-disciplinary, collaborative and capacity building platform undertaking relevant science, including updating technology, with the aim to develop ecosystem indicators that can be used to effectively monitor and understand the Southern Benguela. These include physical, chemical, planktonic, microbial, seabird, marine mammal, benthic and pollution (plastic) ecosystem indicators as required by ecosystem-based management regarding the following priorities: ocean warming, ocean acidification, trophic functioning, pollution and water quality. It is on-going monitoring programme.
