"This second annual report to the Texas Water Development Board includes data collected from July, 1973 to April, 1974 by the University of Texas Marine Science Institute at Port Aransas, Texas.

This Second Edition of Plankton is a fully updated introduction to the biology, ecology and identification of plankton and their use in monitoring water quality.

Marine ecosystems are changing at an unprecedented rate. In addition to the direct effects of e.g. warming surface temperatures, the environmental changes also cause shifts in plankton communities.

A seasonal quantitative study of plankton and a survey of profundal benthic macroinvertebrates were conducted during the open water period in Grander Lake, Newfoundland.

Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic. This book presents the latest research in the field from around the world.

Due to taxonomic difficulties in the early collection months, a back-log of samples was built up, preventing the inclusion of July and August data in this report. This data will be included in the next annual report.
