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.     

Testing for the Law of One Price and Identifying Price-Leading Markets: An Application to Corn Markets in Benin

A data-determined method is proposed to test for the law of one price as a long-run equilibrium condition and to identify which markets in a network of spatially dispersed commodity markets quote the reference price. The method consists of supplementing Johansen's FIML cointegration procedure with a permanent-transitory decomposition and rules of inference in linear time-series models with unit roots. As an example, we apply our method to prices of six corn markets in Benin. We find that the law of one price holds in the long-run. It appears that two rural markets quote the reference price: their prices adjust fastest towards the permanent change induced by the common stochastic trend.     

The Search for the 1871 Whaling Fleet of the Western Arctic: writing the final chapter

During 2015, the NOAA Office of National Marine Sanctuaries led a systematic seabed mapping survey along the Arctic coast of Alaska in search of whaling ships abandoned in 1871. The purpose of the expedition was to determine if wreckage from these abandoned ships was still present in the survey area, and, if so, to assess and document its location, status and condition. The project mapped approximately 50 km² of seabed using sidescan sonar and magnetometry and identified six sites that contained wreckage from at least two whaling ships. Magnetometry data also suggested that additional wreckage may be buried in the seabed.     

Mimi Pinson Goes to War: Taste,Class and Gender in France, 1900–18

In the years leading up to the First World War, the Frenchwomen of a free performing‐arts programme for female workers, known as the Mimi Pinsons, began to appear frequently in popular stories, articles, poems and songs as cultural shorthand for a renovated social vision of France. Founded by composer and philanthropist Gustave Charpentier in 1900, the Oeuvre de Mimi Pinson taught its worker–students elementary music, song and dance, and gradually expanded to include a charitable organisation and social network. A closer examination of the OMP reveals that its members were also used to reconcile early twentieth‐century French anxieties about working‐class militancy and even war by way of a potent cultural association of female sexuality, aesthetic refinement and labour. In the years before the First World War, the Mimi Pinsons were defined by journalists, government officials and the OMP's own organisers according to a formulaic type which at once modernised and constrained the role of the female Parisian worker. Associated almost exclusively with the luxury‐garment trades – seamstresses, flowermakers, milliners and department‐store clerks – the new Mimi Pinsons were embraced by the public as naturally chic yet diligent guardians of French art and craft. These female worker–students allowed an easy merging of the body of the female worker with particularly French notions of the patriotic responsibility of feminine taste. When the First World War came, many of the Mimi Pinsons joined the war effort as workers and nurses, yet they were embraced by the public primarily for their service as tasteful creators of patriotic decorative objects, and as an ideal symbolic figure for managing anxieties about the social dissolution that came with the war.     

Identification of a Deep-water B-29 WWII Aircraft via ROV Telepresence Survey

American-produced B-29 Superfortress bomber aircraft flew missions against Imperial Japan in the Pacific Theater from air bases in the Mariana Islands from November 1944 until the end of WWII. Mechanical failures forced many B-29s into the ocean surrounding Saipan and Tinian. Terrestrial wreckage of these aircraft has been located in the Pacific region, but no losses in deep water were located until 2016, when a NOAA exploration cruise investigated sonar targets in the Saipan Channel, between Saipan and Tinian. Disarticulated wreckage from a B-29 was located at 370 m over a large area of the seabed. Telepresence-enabled, non-invasive exploration from NOAA Ship Okeanos Explorer allowed scientists on shore to view live streaming video and to work collaboratively to guide the investigation. Experts in aviation archaeology, corrosion studies, WWII history, forensic studies, marine biology, and oceanography participated in the survey using an ROV, highlighting components which could lead to possible identification of the B-29 in situ, and conducting an environmental characterization of the site. This deep-water aircraft site exemplifies multiple-stakeholder driven research in aviation archaeology and highlights several issues in the value of individual site identification.
