“…In any case, common galaxias ( Galaxias maculatus [Jenyns, 1842]) dominated the freshwater fish fauna existing 1,278–1,013 cal years BP at Tierra de Fuego, as salmonids had not been introduced yet (Cussac et al, ). Common galaxias migrate to estuaries to spawn and Bahía Cambaceres Interior had a strong estuarine influence 1,278–1,013 cal years BP (Zangrando, Ponce, et al, ), thus suggesting the existence of a higher connectivity between freshwater and marine ecosystems in the Beagle Channel 1,278–1,013 cal years BP. Ancient cormorant from other archaeological sites in the Beagle Channel had stable isotope ratios more consistent with a marine diet (Kochi et al, ), but the ancient cormorant from Lanashuaia II may have relied largely on migratory common galaxias spawning in the area (Casaux et al, ).…”

“…Currently, snoek inhabits the coastal waters of the cold temperate Southern Hemisphere with SST between 13°C and 18°C (Bianchi et al, ), including Chile (Bahamonde, ; Duarte et al, ), the western Atlantic coast of South Africa (Griffiths, 2002, ; Isaacs, ), the southern coast of Australia and the coast of New Zealand (Augé, Lalas, Davis, & Chilvers, ; Mehl, ). Nowadays, snoek is absent from the coasts of Argentina and the subantarctic waters of the Beagle Channel, where the SST is between 5°C and 10°C (Lloris & Rucabado, ; López et al, ; Zangrando, Ponce, et al, ). The presence of snoek in the Beagle Channel throughout the Late Holocene (Orquera & Piana, –1994; Tivoli & Zangrando, ; Zangrando, ; this work) strongly supports the hypothesis that SST was higher than currently during most of the Late Holocene.…”

“…The species composition of the marine animal community inhabiting the Beagle Channel has been rather stable during the second half of the Holocene (Tivoli & Zangrando, ; Zangrando & Tivoli, ), although snoek ( Thyrsites atun [Euphrasen 1791]) is currently absent from the area (Lloris & Rucabado, ; López, García, & San Román, ; Zangrando, Ponce, et al, ) and seal populations are well below carrying capacity as a legacy of commercial sealing (Crespo et al, ; Grandi, Dans, & Crespo, ).…”

Stable carbon and nitrogen isotope ratios in the skeletal elements of both ancient and modern marine species from the Beagle Channel were used to compare the structure of Late Holocene and modern food webs, and predict potential changes as a result of a Sea Surface Temperature (SST) increase in the region. Complementary, ancient and modern shells of limpets and mussels were isotopically analysed to explore changes in the isotopic baseline and compare marine food webs through time after an appropriate correction for baseline shifts. Results confirmed a declining pattern of marine primary productivity during the Late Holocene in the Beagle Channel. In general, the isotopic niches overlapped largely in the ancient food web in comparison to the current marine one, with the exception of that of cormorants (Phalacrocorax sp.). Our data suggest that all the species that have undergone intense human exploitation (Arctocephalus australis, Otaria flavescens and Merluccius sp.) significantly increased their trophic levels. The most important finding of this work was the very high isotopic overlap between snoek (Thyrsites atun) and hake (Merluccius sp.) during the Late Holocene. Increasing SST as a result of global warming could favour the recolonization of the southern South‐Western Atlantic Ocean by snoek from the South‐Eastern Pacific Ocean, with a potential impact on the landings of the economically important Argentine and Austral hake. These findings highlight the relevance of using zooarchaeological remains for providing predictions about marine food webs changes in the near future.

“…Coastal landforms in the Cambaceres Bay perimeter indicate that the sea level reached 5 m a.s.l. during the middle Holocene (Zangrando et al, 2016). Geomorphological and chronological data also indicate the formation of coastal landforms during the Holocene transgression maximum in this area of the Beagle Channel.…”

Spatial patterning and occupation dynamics during the Early Holocene in an archaeological site from the south coast of Tierra del Fuego: Binushmuka I

et al. 2018

We explore the implications of the spatial structure of the artifact assemblages at the Binushmuka I site, located in the north coast of the Beagle Channel (Tierra del Fuego). The information corresponding to the stratigraphy, chronology and composition of the archaeological assemblages of this site is described. We focus on the spatial distribution of artifacts, which mainly depend on the number and duration of the occupations and the size of the group, to evaluate the temporal structure of the assemblages. For assessing pattern mobility, we also consider the spatial consistency of the location of the site in relation to features of the paleogeography and the archaeological landscape. The confined size of the assemblages (~7-8 m 2) are likely to represent occupations by small sized groups. The spatial consistency between early Holocene occupations and marine hunter-gatherer assemblages observed at a regional level suggests that groups with similar mobility and foraging strategies could have occupied the site.

LiDAR has become fairly integrated into archaeological practice at a global scale. This has gradually evolved to include UAV LiDAR. Nevertheless, considerable biases remain, including with regard to geographical regions, chronological periods, feature types and environments. At present, few studies of coastal environments exist, despite the fact that LiDAR—and UAV LiDAR in particular—has the obvious advantages of flexibility and time efficiency in such archaeologically rich but logistically challenging environments. In this paper, we compare the results of UAV LiDAR surveys with records from previous ground surveys in two case studies from coastal environments on opposite sides of the globe. Case Study I of shell middens located within approximately 3 km2 around Cambaceres Bay involved the first collection of LiDAR data from Tierra del Fuego, Argentina. Case Study II covered approximately 3 km2 of the island of Vega, Northern Norway, and is among the pioneering LiDAR studies of Mesolithic house pits. The detection success rate was fairly good for Cambaceres—69% of 1240 recorded structures were identified on LiDAR—and above expected for Vega, with 81% of 51 recorded house pits identified on LiDAR. In Cambaceres, the main challenges were dense and low vegetation and identifying small middens. Possible new identifications of archaeological features were made in both areas: subtle depressions interpreted as dwelling foundations in Cambaceres and house pits on Vega. We conclude that UAV LiDAR can contribute to coastal archaeology and that it has added values besides making new identifications, being both flexible and time efficient. An example pertains to the possible identification of a practice that has not previously been proved archaeologically in Tierra del Fuego—more thorough site preparation prior to the construction of the dwellings—which in turn raises new questions.
