Doubious tag, Project Magnet & Pioneer survey
See Talk:Ron G. Mason for details. Project Magnet was an aeromagnetic survey program and not "highly classified" as stated. Neither was it directly tied to submarines but collected world wide magnetic data going to "support navigation of ships and aircraft and to meet Naval requirements as well as scientific research" and it was a publicized program with purpose and data not generally classified. The project was under the Navy's Hydrographic Office at the time with flight by a special squadron.

The "highly classified" — with no clear reference and not removed solely as a place mark for clarification with references about the Pioneer work of that time — may actually be accurate for the ship's work. The West Coast Sound Surveillance System (SOSUS) was underway with pre-installation survey work under Project Caesar. That project was, though not particularly "highly" classified, very tightly held with very strict need to know so that many even in Navy involved did not know "why" things were being done. The Hydrographic Office in the early days of the project managed the surveys and would have been the official sponsor of the Pioneer survey and thus the approval authority for Mason's involvement.

Page revised with cites for joint Navy effort with Scripps participation with regard to magnetic device and data collection. Footnote that explains the "highly classified" association — though not in any way with Project Magnet (which was rather public with its aircraft gaining some fame). Project Caesar was the unclassified cover name for SOSUS installation and support and, though not "highly classified" was very tightly controlled within Navy so that even personnel involved in its operations often did not know the purpose or associations (See SOSUS). The confusion is an excellent example of how old classifications and their cover stories can create a "fog" of project and operation associations, names and purposes with some persisting in publications and popular media for very long periods.

Reference blunder & reliability
If the link is an accurate reflection of the published book the reliability of the reference, Krakatoa: The Day the World Exploded: August 27, 1883 becomes questionable with regard to details of the operation. Too many major blunders with respect to this subject in the applicable paragraph: Uh, uh! If an author cannot find that the ship Pioneer was USC&GS, not USCG, the whole bit becomes questionable as to accuracy of the author's research regarding the project and ship operation. While it is possible Mason erred in assuming Project Magnet included shipboard surveys (others made such mistakes) he certainly knew the ship was USC&GS. The author with a few keystrokes and a search engine would have known better as well. (The previous is copied from Talk:Ron G. Mason) The role of Mason in obtaining permission is also overemphasized. Actual permission was gained by Roger Revelle interacting with John Lyman, then Director of the U.S. Navy Hydrographic Office's Division of Oceanography, who took the proposal to the Hydrographer of the Navy for permission. More detailed and reliable sources are available. The book's author may be accurate on other matters, but blunders call the author's research and accuracy regarding Mason's role, the magnetometer and ship into question.

 * "Over coffee one morning he asked whether it might be possible for him to join Project Magnet, as it was called and, without interfering with the government work, to tow a magnetometer behind the project's ship and make his own maps of any magnetic anomalies he might find down on the sea-floor. The project director agreed: and that summer Mason arranged for a long, floating, fish-like object – known formally, in the kind of language heard in science fiction, as an ASQ-3A fluxgate magnetometer* – to be towed behind the US Coast Guard's ship Pioneer as it searched for seemingly more important things on behalf of the Pentagon."

Dominic Swordfish
While reviewing a Defense Nuclear Agency archived pdf on Operation Dominic I found a reference to the USC&GS Pioneer. So I came here and found the article mentioned what the Pioneer did in Dominic, but it made it sound as if there were multiple underwater tests. In fact there was only one such test: Swordfish. I have corrected the grammatical number to singular, added wlinks to Dominic and the Swordfish test by USS Agerholm, and a citation to the Defense Nuclear Agency archived pdf.
