Abstract:

Batch cultures of Isochrysis galbana (strain CCMP 1323) and Chrysotila lamellosa (strain CCMP 1307) were grown at salinity ca. 10 to ca. 35 and the alkenone distributions determined for different growth phases. UK'37 values decreased slightly with salinity for C. lamellosa but were largely unaffected for I. galbana except during the decline phase. The values decreased with incubation time in both species. The proportion of C37:4, used as proxy for salinity, increased in both species at 0.16-0.20% per salinity unit, except during the stationary phase for I. galbana. C37:4 was much more abundant in C. lamellosa (30-44%) than in I. galbana (4-12%). Although our results suggest that salinity has a direct effect on alkenone distributions, growth phase and species composition will also have a marked impact, complicating the use of alkenone distributions as a proxy for salinity in the marine environment.
