All Atlantic ocean sampling day South America

The study of the marine microbiome is essential to understanding the health of our oceans and their impact on the planet. These microorganisms play a crucial role in the regulation of biogeochemical cycles, oxygen production, degradation of pollutants and the marine food chain. In addition, the marine microbiome influences the global climate and is a valuable resource for biotechnology and medicine. Investigating this microscopic world helps us protect our marine ecosystems and address urgent environmental challenges.
DNA analysis through techniques such as amplicon sequencing (metabarcoding) allows the identification of both prokaryotic and eukaryotic microbial species in water samples. Metagenomics, on the other hand, gives us the ability to sequence all the genes present in the microbiome, providing information about gene abundances involved in metabolic pathways (profiles functional) and at different taxonomic levels (taxonomic profiles). Ocean Sampling Day (OSD) is a global scientific campaign that aims to analyze marine biodiversity and microbial function using molecular sequencing techniques. This dataset contains 2 occurrences that were taken in Puerto Colombia and Barranquilla the 9th of september 2023, both are identified up to domain Eukarya and Prokaryota.

海洋微生物组研究对于理解海洋健康及其对地球的影响至关重要。这些微生物在生物地球化学循环调控、氧气生成、污染物降解及海洋食物链中扮演核心角色。此外，海洋微生物组影响全球气候，是生物技术与医学领域的宝贵资源。探索这一微观世界有助于保护海洋生态系统，应对紧迫的环境挑战。
通过扩增子测序（宏条形码，metabarcoding）等技术开展的DNA分析，可识别水样中的原核与真核微生物物种。另一方面，宏基因组学（Metagenomics）能够对微生物组中所有现存基因进行测序，提供代谢通路相关基因丰度（功能谱）及不同分类水平（分类谱）的信息。海洋采样日（Ocean Sampling Day, OSD）是一项全球性科学活动，旨在利用分子测序技术分析海洋生物多样性与微生物功能。本数据集包含2023年9月9日于哥伦比亚港（Puerto Colombia）和巴兰基亚（Barranquilla）采集的2个样本，均已鉴定至真核域（Eukarya）与原核域（Prokaryota）水平。
