growth, photosynthesis, enzyme activities, and UV-absorbing compounds

This dataset contains physiological and carbonate chemistry data for the green macroalgae species Ulva fasciata Delile, collected from the Mediterranean coast of Mersin, Türkiye, in March 2014 and cultured under controlled laboratory conditions. The experiment was conducted using a factorial design comprising two pH levels representing ambient pH and reduced pH conditions, and two irradiance treatments: PAR and PAR + UVA + UVB. The dataset includes daily growth rate, chlorophyll a and b, photosynthetic parameters, carbonic anhydrase and nitrate reductase activities, UV-absorbing compounds, and seawater carbonate chemistry parameters calculated using CO2SYS.
