Variability in the chlorophyll‐specific absorption coefficients of natural phytoplankton: Analysis and parameterization
TL;DR: In this article, the chlorophyll (chl) a-specific absorption coefficients of living phytoplankton aph*(λ) were analyzed using a data set including 815 spectra determined with the wet filter technique in different regions of the world ocean.

A method for the continuous measurement of in vivo chlorophyll concentration
TL;DR: In this article, a modified model III Turner fluorometer at sea was used to continuously measure chlorophyll from 0·04 to between 10 and 15 mg m −3, a range adequate for all open ocean studies.

Absorption of light by chlorophyll solutions
TL;DR: This paper deals with the estimation of chlorophyll in plant extracts by application of absorption coefficients of the isolated solid chlorophylla components, and the question of artifacts is automatically clarified.

Criteria for purity of chlorophyll preparations
TL;DR: The primary purpose of this paper is to establish satisfactory criteria for several chlorophyll preparations, especially with reference to their absorption of light, of fundamental importance in assays of pigment mixtures by spectroscopic means.

Phytoplankton Nitrogen in the Oceans1
TL;DR: The ratio of cellular nitrogen and chlorophyll has been studied in cultures of marine phytoplankton during and after recovery from nitrogen deficiency; however, the ratio was only constant when the cells were sufficient in nitrogen.

The chlorophylls in vivo and in vitro
TL;DR: In this paper, a special property of the absorption spectrum and of the molecular structure of chlorophyll, which gives us an indication as to why this dye is unique in the promotion of the photochemical reactions of photosynthesis, is discussed.

Determination of chlorophyll derivatives in marine sediments
Wilson L. Orr,John R. Grady +1 more
TL;DR: In this article, a rapid method is given for routine determination of acetone-soluble chlorophyll derivatives in marine sediments, extracted from 10-100 g of wet sediment by acetone and transferred to chloroform for spectrophotometric determination.
