This second edition of An Introduction to Ocean Remote Sensing by Seelye Martin has all the fine attributes of the first edition, and also provides an excellent update on the long-term remote sensing of ocean properties from space. It covers several innovative new remote sensing satellites that were launched or began to produce results during the 10 years between the two editions. This review concurs in most details with my review of the first edition published in Oceanography a decade ago (http://www.tos.org/oceanography/archive/18-3_katsaros.pdf). Here, I aim to point out both changes and new information provided in the second edition. For instance, the first edition’s section on further developments was eliminated for the second edition because most items in the original list of future satellites have come to fruition. There are still developments to come in the near future, but information about them is now sprinkled throughout the text.
