Heritage steamboat Nenana at Pioneer Park, Fairbanks, Alaska  (J. Pollack 2017)

 

Research Associate John Pollack has just returned from Alaska where with the assistance of City of Fairbanks staff a hull assessment was conducted of the heritage ship Nenana. The 210’ Nenana was one of the last and largest American-built stern-wheel steamboats to work on the lower Yukon and Tanana Rivers, where it served as a packet carrying up to 52 passengers and towing 6 barges at a time. The standard two-week route was a 1600 mile round trip to Marshall, with the occasional trip above the Arctic Circle to Fort Yukon. Nenana is the only known example of a northern wooden-hulled  sternwheeler designed by naval architect W.C. Wickum in 1932 and built from blueprints. The goal was to create a powerful, minimum draft tow boat suitable for the shallow, lower sections of the Yukon River drainage. The ship has a barge-like hull with standard chine construction, a rectangular cross-section amidships and a broad bow. The blocky hull is visibly less sophisticated than the streamlined Klondike 2 which carried freight cargo on the main deck, and towed only a single barge through the more constricted and meandering sections of the upper Yukon drainage. Another significant difference from Klondike 2, was the use of very few water-tight bulkheads on Nenana.

Several rare examples of hull architecture and machinery were documented, including novel snag deflector arcs designed to keep debris away from the four main rudders, an uncommon slaved tiller assembly placed just inches above the main deck, and the largest number of large transverse beams yet found in a Yukon River steamer. Nenana also contained the second known example of an internal hog post and chain system installed below the main deck, and used to correct hull weakness (e.g. hogging) in the original design. Additionally, the team discovered a truly unique and baffling framing method at the stern rake (or apron), where an upper set of floors (complete with limber holes) was installed above the centerline and side keelsons, which in turn rests upon the lower floors to which the hull planking is spiked. These elevated floors are not shown in the blueprints, suggesting they were an “on-the-fly” alternation made by the shipwrights when the prefabricated hull was assembled in Nenana, Alaska.

 

Largest shipwreck at the Golden site

 

In late September, three additional small stern-wheel steamboat sites were confirmed on the Upper Columbia River between Fairmont and Golden BC, by Danish-Canadian archaeologist Xenius Nielsen and Research Associate John Pollack. The Fairmont site lies a kilometer north of the source of the Columbia River at a point where the river is less than 15 m wide. The Golden sites are 100 km further north (downriver), and plans are being made to document the largest of the three during low water in the spring of 2018. Note the fresh grizzly bear tracks in the mud.

Eight New Shipwrecks Discovered in Greece’s Fourni Archipelago https://nauticalarch.org/eight-new-shipwrecks-fourni/ Mon, 31 Jul 2017 16:21:22 +0000 http://nauticalarch.org/?p=11388

The 2017 season of the Fourni Underwater Survey in Greece fully documented 14 sites located during previous seasons. While the focus of this season was the thorough documentation of sites located during the 2015-2016 seasons, the survey of shipwrecks in the small archipelago led to the discovery of eight new sites, for a total of 53 shipwrecks located over three seasons.

The fieldwork was conducted during three weeks in June by the Ephorate of Underwater Antiquities/Hellenic Ministry of Culture and Sports in cooperation with RPM Nautical Foundation. The research vessel Hercules conducted seafloor mapping using multibeam sonar and inspected deepwater targets with an ROV, while diver teams conducted photogrammetry, drawings, and recovered key artifacts for further study and scientific analysis. The ROV and divers occasionally worked in tandem to record and recover artifacts from sites. Amphoras from each wreck were raised for conservation, archiving, and 3D modeling, and a few were prepared for DNA and residue analysis, as well as testing a new method of direct dating of ancient ceramics.

The eight new sites span the Classical Period through the 19th century A.D. The majority date to the Late Roman period, but the most significant wrecks include a Classical shipwreck carrying amphoras from Chios and a Roman shipwreck transporting Dressel 28 amphoras from Iberia. The project also found a wide range of anchors dating from the Archaic Period through the Byzantine Period. The finds further illuminate maritime connectivity between the entirety of the Mediterranean and reveal trade and technological changes throughout history.

Nicholas Budsberg: Shipwreck Excavation at Highbourne Cay, Bahamas
The 2017 Claude Duthuit Archaeology grant was awarded to Nicholas Budsberg to excavate what may be the earliest known European ship in the Americas, dated to the beginning of the Age of Exploration (1492-1520). In 1986 INA partially excavated the wreck, which is likely either an Iberian caravel or nao, but modern methods will ensure an improved study of the hull.

INA’s 2017 Fieldwork & Research Projects https://nauticalarch.org/inas-2017-fieldwork-research-projects/ Mon, 06 Feb 2017 19:42:26 +0000 http://nauticalarch.org/?p=7456 In 2017, the Institute of Nautical Archaeology will support more than 20 new and continuing archaeological projects around the globe. Much of this research is driven by the graduate students (both current and former) and faculty members of Texas A&M University’s Nautical Archaeology Program, as well as INA Research Associates. Among the projects which received INA funding or support for 2017 are:

Shipwreck Excavation at Highbourne Cay (Bahamas)
Nicholas Budsberg (Texas A&M University)
The 2017 Claude Duthuit Archaeology grant was awarded for the excavation of what may be the earliest known European ship in the Americas, dated to the beginning of the Age of Exploration (1492-1520). In 1986 INA partially excavated the wreck, which is likely either an Iberian caravel or nao, but modern methods will ensure an improved study of the hull.

Underwater Survey in Fourni (Greece)
Peter Campbell and George Koutsouflakis
This survey made headlines in 2016 when archaeologists discovered 45 shipwrecks after just 33 days of diving. The Fourni Channel is the safest of three north-south sailing routes in the eastern Aegean Sea, resulting in a large volume of traffic passing the archipelago. This year, they will undertake 3D mapping of each site, artifact collection, and multibeam remote sensing. INA is delighted to lend support to this important project! Learn more here: Fourni Underwater Survey.

 

Burgaz Harbors Research Project (Turkey)
Numan Tuna (Middle East Technical University), Elizabeth S. Greene (Brock University), and Justin Leidwanger (Stanford University) 

Pending permission from the Turkish Ministry of Culture and Tourism, this collaborative initiative with Brock University, Stanford University, and Middle East Technical University will explore the four harbors associated with the Archaic through late antique maritime site of Burgaz on the Datça Peninsula, Turkey. Begun in 2011, the co-directors of this project are conducting an ongoing comprehensive survey and excavation of the four harbors and associated onshore port facilities. Learn more here: Burgaz Harbors Research Project.

Underwater Archaeology of the Roman Site Kaukana (Sicily)
Massimo Capulli (University of Udine)
In the stretch of Italian coast between Punta Braccetto and the seaside village of Casuzze exist several landings and coastal shelters which delineate the Greco-Roman site of Kaukana, which is connected to trade routes between the East, Tripoli, Egypt, Rome, Malta, and Sicily. This sheltered harbor persisted through the Byzantine, Arab, and Norman eras. The aim of the Kaukana Project, born from a partnership between the Department of Humanities and Cultural Heritage of the University of Udine and the Sea Superintendence of Sicily, is to survey the site for underwater cultural heritage and reconstruct Kaukana’s relationship with the rest of the Mediterranean.

Marzamemi Maritime Heritage Project (Sicily)
Justin Leidwanger (Stanford University)

This collaborative excavation, survey, and heritage management initiative focuses on the maritime landscape and seaborne communication off the southeast coast of Sicily (Italy). The concentration of accessible sites here and their location at the intersection of the eastern and western Mediterranean facilitates inquiry into long-term structures of regional and interregional maritime exchange from the early Roman era (3rd/2nd c. BC) through Late Antiquity (6th/7th c. AD). Learn more here: Marzamemi Maritime Heritage Project.

Sutiles Project – an Examination of Roman-era Laced Boats (Italy)
Staci Willis (INA)
The Sutiles Project, a collaboration between the Department of Humanities and Cultural Heritage of the University of Udine and the Superintendency of Archaeology, Fine Arts, and Landscape of Veneto, aims to study the Roman-era laced hull remains of northeastern Italy through the continued examination of the hull remains of laced boats found along the northwestern Adriatic coast (in northeastern Italy) and the associated excavation records of these remains. So far, this research has uncovered a consistent pattern of identifiable construction features and materials usage that distinguish these vessels as a separate tradition of laced boatbuilding in this region during the Roman imperial period.

Archival Research of Venetian Shipwrecks in the Levant (Venice)
Renard Gluzman (Tel-Aviv University)
The principal objective of this project is to make possible the detection and identification of shipwrecks, by matching archaeological finds with evidence found in Venice’s historical records, and to provide new evidence of shipwrecks unknown to underwater archaeologists. As most databases of ancient shipwrecks are primarily based on archaeological finds, this project aims to supplement existing knowledge with written evidence as a tool for archaeologists to incorporate historical data. Since 2015, 535 indications of shipwrecks concerning Cyprus and the Levantine coast have been documented and incorporated into an online database.

Sudjuradj Shipwreck Excavation (Croatia)
José Luis Casabán (Texas A&M University)
This projects aims to complete the excavation, digital recording, and analysis of the hull remains of the San Girolamo, a 16th-century Ragusan shipwreck which sank in 1576 at the entrance of Sudjuradj Bay on the Island of Sipan (Croatia). A preliminary survey and two partial excavations have been carried out since 2014 to document the hull remains of the 25 meter-long ship, which lies at a depth of 27-30 meters. The San Girolamo represents an unique example of the naval technology of the Republic of Ragusa (Dubrovnik) during the Renaissance period. The study of its hull remains will provide a better understanding of Ragusan seafaring during the 16th century, which encompassed the Ottoman and Spanish empires on both sides of the Mediterranean.

Turtles and Maritime Networks of Trade Project (Grand Cayman)
Megan Hagseth (Texas A&M University)
This study seeks to understand the cultural implications of sea turtle consumption during the 17th and 18th centuries, examining faunal assemblages from shipwreck sites, turtle fishing camps, port communities, and others and comparing this data to the historical record.  In particular, the butchery and distribution patterns have the potential to differentiate elite turtle feasting from common consumption. A secondary goal of the project is to better understand the political and cultural events which directly contributed to the over-hunting of sea turtles and the depletion of the population.

Yukon River Steamboat Survey (Canada)
John Pollack (INA)
When the Gold Rush exploded in 1897 A.D., West Coast shipyards responded to the demand, and stern-wheelers were constructed in yards as far south as San Francisco and as far north as Dutch Harbour in the Aleutian Islands. In total, 266 stern- and side-wheeled steamboats operated on the Yukon River in Alaska and Canada. When the boom dissipated in 1900 A.D., many steamship companies either went bankrupt or were bought out by competitors, and vessels were left derelict on shore. As a result, the Yukon now contains one of the greatest intact collections of stern-wheel vessels known to exist. The Yukon River Project, initiated in 2005, aims to document the range of construction techniques used on these late 19th-century vessels. Learn more here: Yukon River Steamboat Survey.

Sea Biscuit & Salted Beef Research Project (Bermuda)
Grace Tsai (Texas A&M University)
Previous attempts to gauge the nutritional value of shipboard diets were based on historical documentation instead of laboratory data. In this project, shipboard food will be replicated using the exact ingredients and methods of preparation from the 17th century. Archaeological and historical data will be used to replicate the salted pork and beef, ship biscuit, wine and beer, and other provisions aboard Warwick, an English race-built galleon that sank in 1619. Then, a trans-Atlantic voyage will be simulated by storing the food in casks and keeping these in a ship’s hull for three months. Learn more here: Sea Biscuit & Salted Beef Research Project.

Ongoing Projects at INA’s Bodrum Research Center
In addition to the above projects, an impressive array of ongoing post-excavation research projects is based out of INA’s Bodrum Research Center in Turkey. Decades of INA surveys in Turkey have uncovered wrecks and cargoes dating from the Bronze Age to the Ottoman Empire. The most significant of these discoveries have rewritten the history books, adding a staggering volume of data to the archaeological record of ancient and medieval seafaring. Students and scholars from around the world work out of the Bodrum Research Center to survey and study the region’s shipwrecks. Annually, over a quarter of a million paying visitors tour the Museum of Underwater Archaeology where they learn about the important discoveries INA has made with its Turkish partners.
