Raw CTD data from the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) on the Algoa Voyage 209, August 2014

This is raw Conductivity, Temperature, Depth (CTD) data from the Integrated Ecosystem Programme: Southern Benguela on the Algoa Voyage 209, 5 to 15 August, 2014. The Integrated Ecosystem Programme: Southern Benguela (IEP:SB) is a multi-disciplinary, multi-institutional platform to undertake relevant science in the Southern Benguela; also functioning as a platform for collaboration and learning. All projects aim to develop an ecosystem indicator that can be used to effectively monitor and understand the Southern Benguela i.e physical, chemical, planktonic, microbial, seabird and benthic ecosystem indicators, used for ecosystem-based management. IEP:SB focuses on the biologically productive, cold waters of the Benguela Current Large Marine Ecosystem, which are inherently variable on short time-scales and responsive to changing weather patterms. The research aims to provide relevant, reliable and improved assessment of the ecosystem, in support of its effective management,...

Processed underway Thermosalinograph (TSG) observations from SA Agulhas II Voyage 029, December 2017

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 6-second resolution processed TSG data collected, between 08 December 2017 and 13 February 2018, during Voyage 029 on the SA Agulhas II.

Analysed primary production data from the 2017 Integrated Ecosystem Programme: Southern Benguela (IEP:SB) cruises

Analysed Particulate Organic Matter data, Nutrient data and Nitrate isotope data from the 2017 Integrated Ecosystem Programme: Southern Benguela (IEP:SB) cruises conducted in February, May, August and November. IEP:SB focuses on the biologically productive, cold waters of the Benguela Current Large Marine Ecosystem, which are inherently variable on short time-scales and responsive to changing weather patterms. The research aims to provide relevant, reliable and improved assessment of the ecosystem, in support of its effective management, preservation and conservation, so that South Africans can benefit from a healthy and well-functioning ocean environment. The overarching objective is to enhance understanding in process studies by assessing the importance, timing and magnitude of mechanisms and processes that influence the Southern Benguela ecosystem structure and functioning, including the climate variability.

Carbonate chemistry time-series from discrete sampling at thirteen sites in Algoa Bay, South Africa, 2018 - 2020

Coastal monthly carbonate chemistry data and other associated physico-chemical parameters from Algoa Bay, on the temperate south coast of South Africa. Eight offshore and five inshore sites were sampled. Temperature, salinity and dissolved oxygen were measured at each offshore site, and temperature was measured at each inshore site. At each offshore and inshore site, a single sea water sample was collected at the surface for later analysis of pH and total alkalinity (TA) in the laboratory. Remaining parameters of the carbonate system (including pCO2) were calculated in the software program CO2SYS (Lewis and Wallace, 1998) using pH and TA as input parameters. Temperature, salinity, silicate and phosphate concentrations were included in the calculations as supplemental data which may influence carbonate speciation.

State of the marine environment off South Africa: July 2007

Please note: 1. This report has not been peer-reviewed; 2. The conditions of use outlined in the report are superseded by the conditions specified by the License field in this metadata record; 3. The contact information included in the report is superseded by the contact information that can be found in the Responsible Parties field of this metadata record. This is the second in a new series of informal reports introduced in December 2006, intended to provide an overview of marine environmental conditions off South Africa. The reports are based on data from a variety of sources, including web sources, satellite sensors, the South African Weather Service, MCM's coastal and moored instruments and MCM's research cruises and inherent to all of these there is an inevitable lag between the time of data capture and the time when the data first become available for use. The lags are all different. For example, wind data from the Cape Point lighthouse is updated monthly, the moored...
