The November 2014 SOLOMONS and Sealark Maritime Exploration Ltd

Ewan Stevenson and Matt Wray

The objectives of this expedition were to interpret the hydrographic results from the Royal New Zealand Navy Operation Calypso surveys in Iron Bottom Sound in November 2011. was involved with these original surveys, providing historical research support and on site identification of sites and planning of sonar survey areas to the Royal New Zealand Navy. In addition, we aimed on this mission to discover new sonar targets, dive them to identify, and archaeologically survey them in Iron Bottom Sound. Phase II of the expedition was to similarly survey WWII aircraft crashed on various islands in the Solomons, with a particular focus on American Skytrain (C-47, R4D or DC-3) aircraft sites.

An intensive programme was developed which relied on precise timing and involved four team members flying in from different countries, the arrival of the expedition vessel from Australia, dive & camera equipment, and a hundred other issues. There was real potential that some objectives would not be met due to bad weather, transport problems (broken engines), accommodation issues, local politics, poor site location information, diving problems, injury, health issues, or airline flight cancellations…

This expedition was a joint effort between and Sealark Maritime Exploration Ltd (SMX). Archaehistoria, operated by Ewan Stevenson, focuses on locating new underwater WWII sites in the Solomon Islands through historical research combined with modern marine sonar technology. Archaehistoria also conducts surveys on WWII land sites such as aircraft and battlefields in the South Pacific. is particularly skilled at producing results and new discoveries in feasible timeframes.

SMX is a company dedicated to mapping the WWII underwater wrecks of the Solomon Islands and particularly Iron Bottom Sound.

This expedition was also a reunion of the wreck-finding team of Brian Bailey and Ewan Stevenson, who together discovered the wrecks of the USS Aaron Ward (DD-483) and USS Seminole (AT-65) in 1994.

A potential result was possible confirmation of an MIA site and subsequent reporting to JPAC in Hawaii.

Islands visited included Guadalcanal, Tanambogo, Gavutu, Tulagi, Floridas, San Cristobal (Makira), Ulawa, Vella Lavella, Baga (Bava), Bellona and Gizo.


The Team

Team 2014 Expedition  Jeremy Hedley

Brian Bailey
Brian has more than half a century of wreck diving experience and is one of the original salvage divers of the Solomons. He is a true legend of South Pacific salvage, having commercially worked many of the Solomon’s wrecks. He dives 200 feet like it is 20 feet. His dive log is thousands and thousands long. He knows every reef and every wreck in the Solomons. This expedition was only made possible by Brian’s incredibly generous support such as bringing his 54-foot research vessel Wyuna to the Solomons from Australia.

Jeremy Hedley
A popular SSI diving instructor from New Zealand with many decades of diving experience.

Dave Moran
Editor and owner of Dive New Zealand magazine, Dave Moran has half a century of diving and underwater photography experience all over the planet, including Antarctica.

Ewan Stevenson
Born and grown up on Guadalcanal, Ewan has been researching the WWII history of the Solomon Islands and diving the wrecks there since he was 8 years old, some 34 years ago.

Commander Matt Wray, RNZN
Currently serving in the Royal New Zealand Navy and has done so for more than three decades. He was Commanding Officer of HMNZS Resolution (A14) during Operation Calypso hydrographic surveys and fisheries patrols in the Solomon Islands in 2011. He is a Category A hydrographic surveyor. His knowledge of sonar systems & imaging, GPS, hydrographic survey, and wreck finding is unparalleled.

Therefore, the team that assembled aboard the RV Wyuna was a formidably talented group, and the combined team skills, hard work, and a whole lot of fun, produced the results below:

Summary of Results

The following sites were archaeological surveyed. Some are existing sites, and some are brand new discoveries. All images by Ewan Stevenson unless credited otherwise. Please note this is not a complete expedition dive log. There were dives which failed to locate targets and those targets roll over to the next expedition. In addition, some dives were aborted due unworkable conditions, high current, etc. Please note no artefacts were recovered from any of these sites.

1. The Gavutu Wildcat. 27 November 2014
Very specific objective with this site was to record in detail the battle damage in the port wing and port front wind screen. This was accomplished.
[Discovered by HMNZS Resolution / Archaehistoria 3 November 2011; bridge sonar technician on duty AHSO Julie Butler. Site identified as Grumman Wildcat on 3 Nov 2011 from sonar image by Ewan Stevenson. Site confirmed as Wildcat by ROV dive on 4 November 2011. First divers: Ewan Stevenson, Graham Jordaan, Vince Misiti, Craig Taylor, Michael “Mick” Harris, Jamie Leigh Pearson, and Norm Rohner on 9 November 2011] identifies this site at this time as LIKELY that of Lt. James E. Swett’s aircraft of 7 April 1943, Marine Fighting Squadron 221 (VMF-221). The plane is Grumman F4F-4 Wildcat, BuNo. 12084, Plane No. White ‘77’. Jim Swett became ‘an ace in a day’ on this day with this aircraft, claiming 8 aircraft shot down and subsequently awarded a Congressional Medal of Honor. After receiving AA friendly fire, he water landed his battle damaged Wildcat off the Florida Islands. This site requires utmost respect from divers to preserve the archaeological integrity of the site. Please do not touch or tamper with this site. In particular, please do not remove any ammunition from the ammo bays, as this information is critically required for archaeological confirmation of the site. ARCHAEOLOGICAL ANALYSIS IS ONGOING ON THIS SITE.

7. Japanese Midget Submarine. 30 November 2014. NEW IDENTIFICATION! Ko-Hyoteki 37
This particular Ko-hyoteki was salvaged by the USCGC Ironwood (WAGL-297) in January 1945. Ko-hyoteki 37 was released from mother submarine I-20 on 19 November 1942 to the West of Iron Bottom Sound. The Ko-hyoteki crew experienced trouble with the depth control system and were unable to carry out an attack on the American shipping roadstead at Lunga Point, so they scuttled the Ko-hyoteki off the West end of Guadalcanal. The Ko-hyoteki 37 crew were Lt. (jg) Toshiaki Miyoshi and PO1c Kiyoshi Umeda.
Divers: Brian Bailey, Dave Moran and Ewan Stevenson
This is the 4th Ko-hyoteki that Archaehistoria has surveyed of the eight used in the Guadalcanal Campaign. Archaehistoria has conducted ten searches for Ko-hyoteki in the Solomon Islands with successful outcome in three cases. One unsuccessful search was conducted off Savo Island in 2011 (see Savo Island sites this website). Ko- Hyoteki midget submarines around the globe (Hawaii, Diego Surez, Rabaul, Sydney, Guam, New Hanover, Guadalcanal, Kiska Island) are a favourite research topic.

11. “The long protrusion” WWII ship wreckage. 3 December 2014. NEW SITE DISCOVERY!

Probably ex-USS Serpens (AK-97)* . 20m long x 2.5m high.
First divers: Dave Moran and Ewan Stevenson [I was hoping this was going to be a Skytrain (DC-3) site but lucked out here].

*Archaehistoria was the first to correctly identify this wreck about 1990. This led Archaehistoria to discover the real USS Seminole (AT-65) wreck site. The Serpens was often erroneously referred to in 1970’s and 1980’s by divers as “the Seminole wreck…” including by the author’s father Charles C. “Jock” Stevenson.

15. Vought OS2U-1 Kingfisher. 6 December 2014
Guadalcanal Island. This site is located at the Eastern end of the island and local oral folk history is that the floatplane was damaged in landing (or take off) whilst coming to rescue downed U.S. aviators. This was probably about 1943 to 1944 timeframe. It is likely the aircraft is from U.S. Navy Scouting Squadron 64 or 68. (VS-64 or VS-68). Does anyone have any ideas about this historical event?

20. Mitsubishi Navy Type 0 Carrier Fighter ZEKE (A6M2). 12 December 2014
Vella Lavella Island. MIA site. This site had suffered severe damage within the last three years due to a European failed partial salvage of wings and engine (now missing). A Japanese party in recent times returned to the site and recovered and cremated the pilot’s bones. It is likely the identity of the pilot is known to the Japanese. It is illegal in the Solomon Islands to salvage or disturb any WWII site. What is the history of this site?

Expedition Summary

This expedition was very successful and met all major objectives. The whole expedition went smoothly with minimal disruptions due weather, etc. Some 29 WWII sites were examined and archaeologically recorded in 27 days. Five significant new WWII underwater wreck sites were discovered in Iron Bottom Sound. Four Skytrain wrecks were planned to be surveyed and all four were successfully located and surveyed. Over 130 videos were made, 250 pages of expedition log written, notes, sketches made, some 4000+ still images taken, dozens of GPS readings, audio recordings of interviews, hundreds of aerial photographs and local information gathered about additional WWII sites (un-surveyed) in the vicinity. In addition to the above, a wealth of experienced gained by the team in deep diving practise with high 02 deco mixes, underwater still image and video recording of archaeological sites, managing sonar surveys, deep low visibility underwater search methods and precisely locating sites. This knowledge can be put to good use in the next expedition. Great results from a great team.

Archaehistoria and SMX are planning the next expedition. We have excellent historical location information on a number of undiscovered marine sites including another MAVIS, a B-17 flying fortress bomber, and a B-24D Liberator bomber.

Besides the above, is considering an expedition to archaeologically survey the WWII wrecks in the big Japanese destroyer and flying boat base in the Shortland Islands in the Northern Solomons say perhaps in November 2016?. This expedition will be looking at land sites as well as discovering new MAVIS and another major shipwreck site in the area and other underwater sites. It would involve chartering a liveaboard, for about 12 days. If you are interested in joining in, let me know.

Expedition Archaeological Material is available
The RAW unedited data per each of the above sites is available as still images and hi-res video for $40 USD on disc including postage.

I would like thank all the team members for making the expedition so much fun and being so dedicated to the ‘cause’.

Crucial research support from the United States of America: James C. Sawruk of Allentown and Sgt. Gene Leslie, USMC (Ret.) of Lake City.

I would especially like to thank my new company boss, Paul Ryan, for letting me take a month off work, just after I started employment at his company, Firetherm Ltd.

Finally I would like to thank my wife, Patrea, for letting me take a month off from family obligations, and assuming all parental duties of looking after our three children, whilst Dad swam 200 feet below Iron Bottom Sound and trekked 1500 feet up a San Cristobal mountain.

Don’t sonar re-search zones of redundant seafloor!
Large portions of Tulagi Harbour seafloor and Lunga Point area of Iron Bottom Sound have now been multi-beam and side scan sonar surveyed. If you are planning to conduct sonar surveys in the IBS area and in the Solomon Islands, don’t waste your time and resources re-surveying the same areas. Please contact me for new areas to explore so the frontier of exploration can be collectively expanded.
