“…Four probes measured the entire 1 yearperiod, one probe from Lighthouse Reef only measured temperature due to malfunction of the conductivity-sensor, and one probe from Glovers Reef was lost. Conductivity (C) was converted into salinity (S) using the practical salinity scale of 1978 (Dauphinee et al 1980;Perkin and Lewis 1980). (Rützler and Ferraris 1982).…”

The Belize atolls-Glovers Reef, Lighthouse Reef and Turneffe Islands-show differences in geomorphology, lagoonal depth, bottom sediment, growth of mangroves and sea-grass, exposure to waves and currents as well as in their sedimentation rates and their age. Bivalve shell assemblages in lagoonal areas reflect these geomorphological differences. On each atoll, 32 to 44 recent sediment samples were taken (total number of samples 111) and bivalve shells subsequently identified. The resulting database (32,122 bivalve shells in total) was analysed using Q-mode cluster analyses. Both the distribution of species characteristic of different lagoonal habitats and the distribution of bivalves with different life and feeding habits were investigated. Epifaunal suspension feeders were found particularly on hard-bottom along the reef-crests or clinging to mangrove roots. Infaunal suspension feeders show a more diverse distribution. Deeper lagoonal parts and areas with mangrove growth are often inhabited by chemosymbiont-carrying bivalves, indicating locations of reduced sediment. Deep burrowing detritus feeders are very abundant in shallow-water areas with moderate to high water agitation and were seldom found in Halimeda-rich sediments.

“…To this end, the mass fraction of the potassium chloride solution which has the same conductivity as standard seawater (with salinity 35) was determined. These measurements were reported by Culkin and Smith (1980), Dauphinee et al (1980a), andPoisson (1980a). Standard seawater obtained from batches P73, P75, and P79 was used to determine the conductivity of (diluted and concentrated standard seawater with) salinities = 35 relative to (seawater with) a salinity of 35.…”

The density–salinity relation of standard seawater

et al. 2018

Abstract. The determination of salinity by means of electrical conductivity relies on stable salt proportions in the North Atlantic Ocean, because standard seawater, which is required for salinometer calibration, is produced from water of the North Atlantic. To verify the long-term stability of the standard seawater composition, it was proposed to perform measurements of the standard seawater density. Since the density is sensitive to all salt components, a density measurement can detect any change in the composition. A conversion of the density values to salinity can be performed by means of a density-salinity relation. To use such a relation with a target uncertainty in salinity comparable to that in salinity obtained from conductivity measurements, a density measurement with an uncertainty of 2 g m −3 is mandatory. We present a new density-salinity relation based on such accurate density measurements. The substitution measurement method used is described and density corrections for uniform isotopic and chemical compositions are reported. The comparison of densities calculated using the new relation with those calculated using the present reference equations of state TEOS-10 suggests that the density accuracy of TEOS-10 (as well as that of EOS-80) has been overestimated, as the accuracy of some of its underlying density measurements had been overestimated. The new density-salinity relation may be used to verify the stable composition of standard seawater by means of routine density measurements.

“…This can be compared to a value of A"RW/hosW = 0.88 calculated (Table 2) from infinite dilution conductivity data (Miller0 1975;Poisson et al 1979;Robinson and Stokes 1965). Part of the difference between the calculated and measured ratio is related to the limitation of the Practical Salinity Scale to S = 2.000 (6) where r = R1J0.0032 (Dauphinee et al 1980).…”

The relative conductivity and density of estuarine waters formed by mixing “world” river water with standard seawater have been determined. The results are used to examine the conductivity‐density‐salinity‐chlorinity relationships of estuarine waters of known composition with seawater diluted with pure water (i.e. the new International Equation of State and Practical Salinity Scale). The maximum difference between the true salinity and the value derived from conductivity was 0.047 in dilute solutions; the maximum density difference between the measured and calculated values was 35 × 10−6 g·cm−3. These results are compared with measurements of waters from the St. Lawrence estuary.
