“…The most accurate present-day measurements of the specific gravity of seawater (Cox, McCartney, and Culkin, 1970) necessitate knowledge of the salinity to five significant digits, e.g., 34.982% 0 (34.982 g/kg). This means that any constituent contributing more than .0001 percent by weight should be accounted for, i.e., all constituents above the part-per-million range.…”

“…More recent work by Cox, McCartney and Culkin (1970) established a new relationship between specific gravity, salinity and temperature. From the above works of Cox and his colleagues at the National Institute of Oceanography, a new relationship between salinity and chlorinity was established, S%" = 1.80655 CI% 0 (3.4) 3-4 as described in UNESCO (1966b), which for CI = 19% 0 and 5%" gives S= 34.325%" and 9.033% 0 respectively (Compare with relations 3.1, 3.2, 3.3).…”

“…The first would measure the temperature and then the salinity using the index of refraction as described above, and then indirectly compute a t through the analytical expression provided by Cox, McCartney and Culkin (1970). This would perhaps be the simplest way.…”

“…The bottles were returned to Specific Gravity the laboratory and stored at 5OC until processing (within 2 h of collection). Salinity was determined using a Goldberg temperature compensated refractometer, and conventional specific gravity was calculated from temperature and salinity (Cox et al 1970). For nutrient analyses, filtrates from rinsed Whatman GF/F filters were collected into acid-cleaned 50 m1 polypropylene bottles and frozen (-20°C) until analysis with a Technicon nutrient autoanalyser.…”

In s~t u comparisons were made In natural microbial populations between the fractlon of partlculate organic carbon (POC) which is particulate protein amino acid (PPAA) carbon, and the fraction of primary producbon allocated to PPAA synthesis This approach was used to examine the relation between protein content of particulate organic matter (POM) and protein metabolism of the photoautotrophic population in the surface muted layer of a marine pond (Salt Pond, Massachusetts, USA) throughout summer 1983 In general, ratlos of algal production of PPAA carbon to total prmary produchon (PPAA-P/P) were similar to ratios of PPAA carbon to total POC (PPAA-C/POC) measured in the standlng POM This ~n d c a t e d that the proteln composition of POM reflected algal blosynthetlc patterns A bloom dominated by the brown flagellate Ohsthod~scus magnus Hulburt occurred in late August On one sampling date dunng the bloom decline, PPAA-P/P was significantly higher than PPAA-C/POC Thls coincided with an mcrease in the pnmary production-related turnover time of the POC pool over that of the PPAA carbon pool and a major s h f t In algal metabolism as evidenced by a change in the pattern of subcellular incorporation of I4C-carbon Evldence to suggest that the bloom population was llght-limited Included decreases in chlorophyll-speclfic production (pB, 1,g C pg Chl a-' h-') and POC/chlorophyll a ratios w h~c h accompanied decreases in the percentages of surface light reaching l m There was also a significant correlation between the dlffuse attenuation coefficient (K m-') and 1n(pR) for the entire summer The difference in PPAA-P/P and PPAA-C/POC ratios was expla~ned by a decrease in pnmary production relat~ve to PPAA production poss~bly due to llght limitation and relating to a physiological transition of the photoautotrophic population Selective removal of PPAA relative to POC by grazers and/or decomposit~on may have also cont~ibuted

“…Millero and Lepple (1973) made measurements on standard seawater (Cl(‰) = 19.374) and artificial seawater from 0 to 40°C. These results were 0.007 ± 0.003 kg m -3 lower than Knudsen (1901), 0.019 ± 0.004 kg m -3 lower than Cox et al (1970), and agreed to 0.002 ± 0.013 kg m -3 with artificial seawater from 0 to 30°C. We attributed the offsets of earlier workers to the water used to calibrate the systems used by Knudsen (1901) and Cox et al (1970).…”
