The currently available instrumental climatic dataset covers only a short period, and the resolution of proxy-based climate reconstructions is low, and these limitations restrict the accurate exploration of glacial changes on the southeastern Tibetan Plateau within the context of long-term climate change. Here, annual-resolution tree ring samples were collected from the oldest pioneer trees (Hippophae rhamnoides subsp. yunnanensis), from the bottom of a glacial valley on the southeastern Tibetan Plateau, and used to reconstruct the glacial changes based on the relationship between the ages of the trees and their distances from the glacier terminal. Results indicate that Zepu glacier has been retreating since 1778 CE, with a total retreat distance of 2757 m and an average retreat rate of 11 m yr-1. The rate of retreat has varied over time, with a maximum of 40 m yr-1 between the 1950s CE and 1970s CE, and glacial retreat has been modulated mainly by temperature variability over interdecadal to centennial timescales. This study provides a new way to reconstruct the history of glacial retreat. #-------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #-------------------- # Site_Information # Site_Name: Zepu Glacier # Location: Asia>Eastern Asia>China # Northernmost_Latitude: 30.2772 # Southernmost_Latitude: 30.2772 # Easternmost_Longitude: 95.2494 # Westernmost_Longitude: 95.2494 # Elevation_m: #-------------------- # Data_Collection # Collection_Name: Zepu2021retreat # Earliest_Year: 1778 # Most_Recent_Year: 2019 # Time_Unit: Year CE # Core_Length_m: # Parameter_Keywords: Other Collections # Notes: #-------------------- # Chronology_Information # Chronology: # #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/PaST-thesaurus/SKOS/past-thesaurus-v1.0.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Variables format: Short_name what,material,error,units,seasonality,data_type,detail,method,data_format,additional_information # ## years age, , , calendar year before present, , other collections, , ,C, age range ## retreat-distance retreat distance, , , meter, , other collections, , ,N, Zepu Galcier retreat distance reconstruction ## retreat-rate retreat rate, , , meter per year, , other collections, , ,N, Zepu Galcier retreat rate reconstruction # #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: # years retreat-distance Retreat-rate 1778-1870 180 2 1870-1897 267 10 1897-1915 91 5 1915-1937 388 18 1937-1953 549 34 1953-1969 640 40 1969-1979 60 6 1979-1995 85 5 1995-2019 497 22 1778-2019 2757 11
