Telepresence-Enabled Maritime Archaeological Exploration in the Deep

Telepresence-enabled exploration of deep sea environments has developed over the past 30 years, providing access to archaeologists, scientists, and the general public to sites otherwise inaccessible due to depth. Pioneered through the inception of the JASON Project in the late 1980 s, telepresence missions have expanded to two dedicated ships of exploration, NOAA Ship Okeanos Explorer and exploration vessel Nautilus, and has been implemented on a series of opportunistic missions on other vessels. This paper chronicles the history of the use of telepresence for the exploration of shipwrecks in deep water as well as how this capability has allowed the public to engage with such missions. Broadening the scope of who can explore the deep sea, telepresence has also expanded what is observed and documented in the deep, which speaks to humanity’s use of the maritime world and an archaeology of discard through our material disposed of into the deep sea.     

Shipwrecks and the Maritime Cultural Landscape of the Gulf of the Farallones

Journal of Maritime Archaeology - The waters of the Gulf of the Farallones are a diverse and expansive maritime cultural landscape that includes at least 400 historically documented shipwrecks....     

ELEMENTS OF SKILL: TRAITS,INTELLIGENCES, EDUCATION,AND AGGLOMERATION*

ABSTRACT There are many fundamental issues in regional and urban economics that hinge on worker skills. This paper builds on psychological approaches to learning to characterize the role of education and agglomeration in the skill development process. While the standard approach of equating skill to worker education can be useful, there are important aspects of skill that are missed. Using a measure of skill derived from hedonic attribution, the paper explores the geographic distribution of worker traits, intelligences, and skills and considers the roles of urbanization and education in the skill development process.     

Archaeological Survey of the Ex-USS <Emphasis Type="Italic">Bugara</Emphasis> (SS/AGSS331)

In August 2017, a multidisciplinary team conducted the first archaeological survey of the deep water (242 m) wreck of the ex-USS Bugara (SS/AGSS331) using the remotely operated vehicles Argus and Hercules. The survey provided 8 h of direct observation with video and still camera documentation of the wreck, which previously had been identified by sonar and a brief ROV survey of portions of the hull in 2001. The 2017 assessment added considerably to an understanding of changes to Bugara after it sank while under tow in 1971. Bugara, a World War II-era submarine, served at the end of that conflict and through the Cold War. The submarine reflects a series of modifications to “modernize” it within the context of the Cold War. The examination of the wreck, along with additional archival research, offers more details not only on the probable cause of the sinking but also on subsequent site formation processes. The characterization of the wreck resulted in a reassessment of the site as more than an obsolete vessel accidentally lost when relegated to target practice. The archival record, now declassified, shows that Bugara’s loss also reflects its ultimate use, within the context of the Cold War, as a target for the Mark 48 torpedo, a newly developed “sub and ship killing” weapon designed in the late 1960s and tested through 1971 to take out Soviet deep-diving nuclear submarines and high-performance surface ships.     

Archaeological Survey of the Ex-USS <Emphasis Type="Italic">Independence</Emphasis> (CVL22)

In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep-water (829 m) wreck of the ex-USS Independence (CVL22) using the remotely operated vehicles Argus and Hercules. The survey provided 34 h of direct observation with video and still camera documentation of the wreck, which the previous year had been initially identified with a limited three-dimensional sonar survey of the site. The 2016 assessment added considerably to an understanding of changes to Independence after its use as a target vessel for the 1946 atomic bomb tests at Bikini Atoll, as a radiological laboratory, training facility, and finally as a receptacle for “nuclear waste” prior to its scuttling off California in January 1951. The location and detailed examination of the wreck, along with additional archival research, offers a more nuanced definition of the carrier’s role within the context of the Cold War between the USSR, its adversaries and the race to establish nuclear supremacy, as well as site formation processes and ongoing biological colonization of the wreck site. As well, no evidence of residual radiological contamination was noted during the mission.     

USS <Emphasis Type="Italic">Independence’s</Emphasis> Aircraft

Submerged aircraft are a newly emerging area of study in underwater archaeology. In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep water (829 m) wreck of the ex-USS Independence (CVL22), a WWII era light carrier scuttled off San Francisco after its use as an atomic bomb test target and subsequently as a floating radiological laboratory and training facility. Using the remotely operated vehicles Argus and Hercules, the expedition documented and studied Independence including assessment of a sonar target thought to be an aircraft resting inside the sunken carrier’s forward elevator pit. The survey confirmed the presence of a plane, but previous assumptions as to the type and identity of this aircraft, based on archival records, proved erroneous. As well, the remains of a second, and possibly a third, aircraft were also encountered during the 2016 survey. These artifacts, through their context, both as naval warplanes on an aircraft carrier, and as test articles for seaborne nuclear weapons development, more precisely fit within the parameters of maritime archaeology. They join other archaeological evidence at the Independence site that helps define its significance within the context of World War II and the Cold War.
