We are happy to inform you about a newly published "Guideline of Ocean Observations" edited and published by The Oceanographic Society of Japan (JOS). The Guideline describes state-of-the-art protocols of the measurement of various oceanographic parameters that cover wide range of oceanographic topics from ocean weather to seafloor observation. The Guideline consists of 64 chapters in 10 volumes, but note that a few of the chapters are currently still in writing. In the process of protocol writing, 30 authors reviewed various existing international guidelines such as ISO, IAPSO and GO-SHIP guidelines, and examined the best protocols for each parameter. For those parameters which are not included in any existing international guidelines, original protocols were newly described by the authors and then reviewed by referees. These guidelines will be useful for oceanographers worldwide, and oceanographers of all countries are invited to use this Guideline as a reference for their ocean observations. The 3^rd edition of all the volumes of the Guideline can be accessed freely and openly as PDFs at: http://kaiyo-gakkai.jp/jos/en/guide/preface
