Abstract:
Abstract. Coccolithophores are potentially affected by ongoing ocean acidification, where rising CO2 lowers seawater pH and calcite saturation state (Ωcal). Southern Patagonian fjords and channels provide natural laboratories for studying these issues due to high variability in physical and chemical conditions. We surveyed coccolithophore assemblages in Patagonian fjords during late spring 2015 and early spring 2017. Surface Ωcal exhibited large variations driven mostly by freshwater inputs. High-Ωcal conditions (max. 3.6) occurred in the Archipelago Madre de Dios. Ωcal ranged from 2.0–2.6 in

Abstract:
As a result of climate change, the frequency of glacial lake outburst floods (GLOF) is increasing in Chilean Patagonia. Yet, the impacts of the flood events on the physics and biology of fjords is still unknown. Current velocities, density, in-situ zooplankton samples, and volume backscatter (Sv) derived from an acoustic profiler were used to explore the response of circulation and zooplankton abundance in a Patagonian fjord to GLOF events in 2010 and 2014. Maximum Sv was found both during the GLOFs and in late winter to early spring of 2010 and the fall and summer of 2014. The increase in Sv

Abstract:
The kelp forests of southern Patagonia have a large diversity of habitats, with remote islands, archipelagos, peninsulas, gulfs, channels, and fjords, which are comprised of a mixture of species with temperate and sub-Antarctic distributions, creating a unique ecosystem that is among the least impacted on Earth. We investigated the distribution, diversity, and abundance of marine macroinvertebrate assemblages from the kelp forests of southern Patagonia over a large spatial scale and examined the environmental drivers contributing to the observed patterns in assemblage composition.

The southern river otter (Lontra provocax) and the marine otter (Lontra felina) are endangered species that inhabit Chile. In southern Chile, both species cohabit with the American mink (Neogale vison), an invasive exotic species. The Chilean aquaculture industry has grown exponentially since the late 1980s, with salmon farming taking place from central Chile to the Patagonian fjords and channels.

Main oceanographic characteristics of Patagonian fjords The Chilean Patagonia (41°-56°S) encompasses one of the most extensive fjord regions in the world (240000 km2) with oceanographic conditions that can sustain unique ecosystems. The region is made up mainly of fjords and channels, characterized by intertangled geomorphologies where water inputs from terrestrial and marine ecosystems overlap and mix (González et al., 2013). Patagonian fjords are characterized by highly complex geomorphology and hydrographic conditions, besides strong seasonal and latitudinal patterns in precipitation, f

Abstract:
AbstractThis chapter explores Chilean tourists’ valuation of tourism experiences in and around the Chilean village of Puyuhuapi. In 2020, local stakeholders were concerned about the impacts that salmon aquaculture infrastructure within the fjords surrounding Puyuhuapi might have on tourism. Research was undertaken to examine how prospective national tourists might perceive visible salmon aquaculture infrastructure within Puyuhuapi’s landscapes. Two hypothetical experience scenarios were designed, with short texts describing possible experiences and visual cues portraying typical destination landscapes. The scenarios were differentiated by the presence of movable floating sea cages. The scenarios were presented to potential tourists through an online survey (n = 804 responses). Results supported current nature-based tourism experience positioning, suggesting it was well received with and without the presence of salmon aquaculture infrastructure. The visible presence of the movable floating sea cages did not provoke significant differences in the valuation of the landscape for prospective tourists; nevertheless, several significant interactions occurred between tourism experience attributes and socio-demographic characteristics, including population density, level of education, and sex. Discussion focuses on defining a series of hypotheses to inform future research and the importance of expanding understanding of Chilean perspectives and imaginaries of Patagonia and its abundant natural settings and values.
