TLDR
In this article, the compositions of sterol, alcohol and ketone fractions from an oxic intertidal surface sediment from Corner Inlet have been examined by capillary gas chromatography mass spectrometry and related to the lipids of diatoms cultured from the sediment and to lipid of the seagrass Zostera muelleri.About:

A review of sterol markers for marine and terrigenous organic matter
TL;DR: It is indicated that inferences drawn from sterol distributions regarding sources of organic matter must be made with caution and should be supported using other lipid data, and that in ancient sediments and crude oils a high proportion of C 29 steranes need not indicate that most of the organic matter was derived from vascular plants.

Molecular stratigraphy: a new tool for climatic assessment
TL;DR: In this paper, the relative abundance behavior of two organic compounds, C37 alkenones over the upper 8 metres of a sediment core from the eastern equatorial Atlantic is inferred from a molecular record, ascribed to contributions from prymnesiophyte algae, which correlates well with variations in the δ18 signal for the calcareous skeletons of certain planktonic foraminifera.

Lipids of aquatic organisms as potential contributors to lacustrine sediments—II☆
TL;DR: The relationship between the lipid composition of organisms in the water column of an eutrophic lake and the lipid compositions of underlying sediments, previously examined for n-alkanols and steroids, is now reported for hydrocarbons, ketones and carboxylic acids.

The biogeochemistry of Ellesmere Lake, U.K.—I: source correlation of leaf wax inputs to the sedimentary lipid record
TL;DR: In this article, the free lipid distributions from Ellesmere Lake sediments taken from two depths, and comparison with leaf-wax lipid distribution from six deciduous tree species around the lake were made in order to assess lipid sources.

Long chain unsaturated ketones and esters in living algae and marine sediments
TL;DR: A series of C37-C39 di-and triunsaturated ketones and methyl and ethyl esters of hexatriacontadienoic acid (C36 : 2) have been previously identified in marine sediments and the coccolithophorid Emiliania huxleyi.

Organic geochemical indicators of palaeoenvironmental conditions of sedimentation
TL;DR: In this article, the role of oxic and anoxic sedimentary environments is evaluated using a combination of geochemical parameters such as lipid composition, sulphur and organic pigments.

Sterols as ecological indicators
Wen-Yen Huang,W. G. Meinschein +1 more
TL;DR: Plots of the C-27, C-28 and C-29 sterol contents of marine plankton, higher plants, soils, and marine sediments form discrete areas in a triangular diagram as mentioned in this paper.

The Hopanoids: palaeochemistry and biochemistry of a group of natural products
TL;DR: Hopanoids are shown to be widely distributed among Bacteria and Cyanobacteria, and their function in cells is probably equivalent to that of sterols in the eucaryote cell : to act as optimizers of the fluid lipid membranes.

Microbial lipids of an intertidal sediment—I. Fatty acids and hydrocarbons
TL;DR: In this article, a detailed study was made of the solvent extractable monocarboxylic, dicarboxylated and hydroxylated fatty acids and n-alkanes in a surface intertidal sediment, and the distributions compared to microorganisms cultured from the sediment.
