This oceanographic dataset was gathered during the TIC-MOC cruise, which was designed to characterize the dynamics of the Brazil-Malvinas Confluence. The cruise was carried on board the R/V Hespérides, with departure from Ushuaia and arrival to Salvador de Bahía. A total of 66 conductivity-temperature-depth (CTD) stations were completed between 8 and 22 March 2015, offshore from the continental platform and within 45°S-35°S and 61°W-50°W.

The atmosphere plays a fundamental role in the transport of microbes across the planet but it is often neglected as a microbial habitat. Although the ocean represents two thirds of the Earth's surface, there is little information on the atmospheric microbial load over the open ocean. Here we provide a global estimate of microbial loads and air-sea exchanges over the tropical and subtropical oceans based on the data collected along the Malaspina 2010 Circumnavigation Expedition.

Article Synopsis
  • The study analyzes the distribution of nano- and microphytoplankton from 145 oceanic stations across major oceans, highlighting the dominance of dinoflagellates and coccolithophores in nutrient-poor surface layers while diatoms are more prevalent in nutrient-rich zones.
  • A principal component analysis reveals key trends including differences in community composition between upper and lower euphotic zones and a gradient showing regions rich in phytoplankton versus those that are poor.
  • Additionally, significant variations in dominant phytoplankton taxa are identified among the Atlantic, Indian, and Pacific Oceans, alongside the presence of diatom-dominated communities in certain areas.

The deep-sea is the largest biome of the biosphere, and contains more than half of the whole ocean's microbes. Uncovering their general patterns of diversity and community structure at a global scale remains a great challenge, as only fragmentary information of deep-sea microbial diversity exists based on regional-scale studies. Here we report the first globally comprehensive survey of the prokaryotic communities inhabiting the bathypelagic ocean using high-throughput sequencing of the 16S rRNA gene.
