    Description: Two extremely halophilic archaeal strains, designated SB29T and SB3T, were isolated from the brine-seawater interface of Discovery Deep in the Red Sea. Cells of both strains were pleomorphic (irregular polyhedrals, ovals, and rods) and stained Gram-negative; colonies were pigmented pink. The sequence similarity of the 16S rRNA gene of strain SB29T with that of its most closely related validly described species (Hfx. sulfurifontis DSM 16227T) and that of strain SB3T with its closest validly described relative (Hfx. denitrificans ATCC 35960T) was 98.1% and 98.6%, respectively. The incomplete draft genomes of SB29T and SB3T are 3,871,125 bp and 3,904,985 bp in size, respectively, and their DNA G + C contents are 60.75% and 65.64%, respectively. The highest ANI values between the genomes of SB29T and SB3T and the most closely related genomes in GenBank were determined as 82.6% (Hfx. sulfurifontis ATCC BAA-897T, GenBank accession no. GCA_000337835.1) and 92.6% (Haloferax denitrificans ATCC 35960T, GenBank accession no. GCA_000337795.1), respectively. These data indicate that the two new isolates cannot be classified into any recognized species of the genus Haloferax, and, therefore, two novel species of the genus Haloferax are proposed: Haloferax profundi sp. nov. (type strain SB29T = JCM 19567T = CGMCC 1.14960T) and Haloferax marisrubri sp. nov. (type strain SB3T = JCM 19566T = CGMCC 1.14958T).

    Description: Samples for phytoplankton and zooplankton abundance analysis, together with relevant physicochemical data, were collected in Saudi Arabian waters of the Arabian Gulf during summer 2017 and winter to early spring 2018. This study was part of the Sustaining VI project, jointly conducted by King Fahd University of Petroleum and Minerals and Saudi-Aramco. Phytoplankton samples were taken from surface waters, fixed with Lugol's iodine solution and analyzed in the laboratory using the Utermöhl sedimentation technique. Tintinnids were identified as part of the phytoplankton analysis as well. Zooplankton samples were collected through 10 minute horizontal tows of a bongo net with a mesh size of 300 µm. The net was equipped with a mechanical flow meter in order to subsequently calculate the filtered water volume and zooplankton abundances. In the lab, samples were analyzed following the method of Postel et al. (2000). Temperature and salinity were measured in-situ, using a YSI multi-parameter sonde. The photosynthetically active radiation was calculated from satellite measurements (MODIS Aqua). Concentrations of total suspended solids were measured by gravimetric analysis. Macronutrients (nitrite, nitrate, phosphate and silica) were analyzed using segmented flow analysis, while trace metals (copper, iron, molybdenum, nickel, vanadium and zinc) were analyzed by ICP-MS.

    Description: Within the framework of the project “Sustaining Research Project, Marine Environmental Studies in the Arabian Gulf – Phase VI”, three coastal stations at Manifa, Khobar and Uqair were sampled monthly for size-fractionated chl a (micro-, nano- and picophytoplankton), as well as for total chl a, and for a range of physico-chemical variables. Sampling started in May 2016, this file includes the data from the first two years.
