INA Webinars

From time to time INA offers the “Wednesday Webinar” in which archaeologists and directors of INA-supported projects deliver online presentations featuring their recent research. The Wednesday Webinars are open to everyone, and we encourage you to consult INA’s Facebook page or this webpage to learn about upcoming webinar presentations.

INA Webinars are recorded only with the permission of the presenter(s); check out these past INA Wednesday Webinars!

Inland Waters & The Legacy of the Erie Canal:
Historical insights from Shipwrecks

On April 27, 2022, INA Affiliated Scholar Art Cohn discussed the early vessels of the Erie Canal. The Erie Canal system opened to vessel traffic in the fall of 1825, and from the very beginning the Canal was successful beyond expectations. The first boats built to transit the new canal moved both passengers and freight, with the “packet boats” revolutionizing passenger travel until the railroads came. In 2018, in anticipation of the Erie Canal Bicentennial in 2025, a new underwater survey was initiated in Seneca Lake, once connected to three early canals. Art will provide a brief historical overview and report on the findings to date.

Phoenix Project:
New Discoveries from the World’s Oldest Steamboat Wreck

On March 30, 2022, INA Research Associate Dr. George Schwarz (Naval History and Heritage Command) presented an INA Wednesday Webinar on the earliest steamboat wreck Phoenix, which sank in Lake Champlain in 1819 and was discovered in the late 1970s. The hull remains were intact for study except for one critical element: there were no signs of the vessel’s iconic paddle wheels. For decades, historians were puzzled by the absence of the vessel’s iconic paddle wheels, but two years ago, a local Vermonter discovered two large discoid objects half-buried in the lakebed a quarter mile away. This presentation relays the history of Phoenix, its archaeological discoveries, and introduces the recent INA investigations of these newly found artifacts – possibly the world’s oldest surviving paddle wheels.

Fifty Years of Nautical Archaeology:
INA in Virginia

On February 23, 2022, INA Scholar in Residence Dr. John Broadwater (Founder & President, Spritsail Enterprises) presented INA’s Wednesday Webinar entitled Fifty Years of Nautical Archaeology: INA in Virginia.” In 1973, INA was newly incorporated and needed to locate shipwrecks that could be excavated in the coming years. INA Founder George Bass (1932-2021) planned a survey to follow ancient trade routes along the southern coast of Turkey. Broadwater participated as sonar operator, diver, and videographer, but neither he nor Bass knew that the 1973 survey would bring them together again in 1976 on a project in Virginia.

The Classical Shipwreck at Tektaş Burnu, Turkey:
An Overview

INA President Dr. Deborah Carlson delivers a joint ARIT-INA-KUDAR webinar about the Classical Greek shipwreck at Tektaş Burnu, Turkey. This small merchant ship was transporting a cargo of wine, pine tar, and Greek ceramics when it sank off the Aegean coast of Turkey around 425 B.C. Carlson helped INA Founder George Bass (1932-2021) excavate the Tektaş Burnu wreck between 1999 and 2001. To view this webinar with closed captioning, click here. This webinar was presented on January 26, 2022.

The Shipwreck at El Sec:
Preliminary Results from 2021

This Wednesday Webinar was presented by Carlos de Juan (University of Valencia). Excavated in the 1970s, the 4th-century B.C. El Sec shipwreck is known for its extensive cargo of Greek pottery marked with Greek and Punic graffiti. The use of explosives and subsequent looting led many to conclude that little was left on the site. The 2021 season was supported in part by INA’s Claude Duthuit Archaeology Grant. This webinar was presented on October 27, 2021.

Forty Years Later: Revealing the Santo António de Tanná,
A Progress Report

Scholar Jeremy Green, former Head of Maritime Archaeology at the Western Australia Museum, discusses the digital reinterpretation of 35mm photographs taken 40 years ago during excavation of the Portuguese frigateSanto António de Tanná, which capsized at Mombasa, Kenya, in 1697.  The Mombasa Wreck was excavated in the late 1970s by a team from INA and the National Museums of Kenya.  These efforts to generate a 3D model of the entire site are supported in part by INA’s George and Ann Bass Publication Grant. This webinar was presented on September 29, 2021.

The Sloop Boscawen and the King’s Shipyard:
Mid-18th Century Shipwrecks in Lake Champlain

The sloop Boscawen was built during the Seven Years’ War as part of a British campaign to counter the French presence in the Champlain Valley. Using Boscawen as a focal point, this presentation explores how colonial shipwrights designed, built, and rigged early sailing vessels for use on Lake Champlain and how Boscawen’s hull construction compares to other watercraft built in northeastern North America during the eighteenth century. This Wednesday Webinar was presented by recent Texas A&M doctoral NAP graduate, Dan Bishop. This webinar was presented on April 28, 2021.

The Cape Gelidonya Shipwreck:
Old Ship, New Methods

The Late Bronze Age shipwreck at Cape Gelidonya, Turkey, where George Bass started it all in 1960, keeps on giving. Seven members of the current research team briefly present what they are learning from the discoveries made on the seabed in the 1980s, 1990s, and 2010, and in the laboratories by means of scientific and 3D analysis. This Wednesday Webinar was presented by Nicolle Hirschfeld (Trinity University) and the Cape Gelidonya team, Nicholas Blackwell (Indiana University), Joseph Lehner (University of Sydney), Emre Kuruçayırlı (Boğaziçi University). Samuel Martin and Lucy Bowland (University of Arkansas), and Dominique Langis-Barsetti (University of Toronto). This webinar was presented on May 26, 2021.
