The Antarctic sea ice reconstruction (CMST-South) based on the optimized Data Assimilation System for the Southern Ocean
<p>The wealth of historical sea ice concentration (SIC) observations, coupled with their extensive spatial coverage, renders them indispensable for the reconstruction of long-term Antarctic sea ice variability. However, recent studies have pointed out the presence of significant uncertainties in certain aspects of Antarctic sea ice reanalyses obtained from assimilating SIC. Notably, while previous studies on ocean data assimilation have already demonstrated the significance of optimizing model-dependent parameters for assimilating oceanic observations, this aspect has received limited attention in current sea ice data assimilation studies. As a result, whether optimizing model-dependent parameters can enhance the effectiveness of assimilating SIC remains an open question. Thus, we address this gap by refining the model-dependent parameters of Data Assimilation System for the Southern Ocean (DASSO), including the development of a latitude-dependent localization scheme and the objective estimation of observation error variance of SIC which takes into account both measurement errors and representation errors.</p> <p>Here, the monthly anomalies in Antarctic sea ice extent and volume (1980 -2018) are uploaded which is produced by the optimized Data Assimilation System for the Southern Ocean (DASSO) with assimilating SIC. Besides, a 13-month moving mean is applied to monthly anomalies to focus on the low-frequency variability of Antarctic sea ice.</p>
Fig. 1 in Nesterenkonia salmonea sp. nov. and Nesterenkonia sphaerica sp. nov., isolated from the Southern Atlantic Ocean
Fig. 1. Phylogenetic analysis of strains GY074T and GY239T and closely related members of the genus Nesterenkonia based on 16S rRNA gene sequences. GenBank accession numbers are given in parentheses. Multiple alignments, distance calculations and clustering with the neighbour-joining, maximum-likelihood and maximum-parsimony methods were performed by using the software package MEGA version 7. Bootstrap values based on 1000 replications are shown as percentages at the branching points. Bar, 0.005 nucleotide substitutions per nucleotide position. Filled circles (●) indicate that these branches cluster similarly using the different test algorithms.
