title: Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934 - 2020

description: The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for recreational activities, businesses, and downstream users, and provide habitat for several threatened or endangered species. The areas pertinent to the recharge process are the catchment area and the recharge zone. The catchment area consists of the parts of river basins upstream from the recharge zone. Streams in the catchment area generally gain water (hence the term "catchment area") as they flow toward the recharge zone. As the streams flow across the recharge zone, which is essentially the outcrop of the Edwards aquifer, they lose substantial amounts of water through infiltration into the highly permeable, faulted and fractured rocks of the outcrop. Direct infiltration of rainfall also occurs in the interstream areas of the recharge zone. Annual recharge estimates are based on data collected from a network of U.S. Geological Survey (USGS) streamflow-gaging stations at sites upstream and downstream from the recharge zone and on assumptions related to applying runoff characteristics from gaged areas to ungaged areas (Puente, 1978). Runoff is affected by the distribution of rainfall, which historically has been estimated from a network of rain gages, some operated by the USGS, some by the Edwards Aquifer Authority (EAA), and some by the National Weather Service. Since 2004, the distribution of rainfall has been estimated from calibrated NEXRAD (NEXt-generation weather RADar) data provided by the EAA. The annual estimation of recharge to the Edwards aquifer is part of a continuing program of the USGS in cooperation with the Edwards Aquifer Authority. This data release is formatted as a tab-delimited file (.txt) that contains the estimated annual recharge to the Edwards Aquifer for 1934 through 2020. The estimated annual recharge is divided into eight major river basins of the catchment area and for some of those basins, will also include estimates of recharge from adjacent ungaged areas.

title: Endeavour South Current Meter Deployed 2012-06-15

description: The Nortek Aquadopp Current Meter A2L2491 AQD2882 was deployed on 2012-06-15 at Endeavour South. This south section of the Endeavour Hydrothermal Vents includes two moorings to monitor the regional circulation. This device is a Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current metres have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

title: <i>Phycocalidia</i> species (Bangiales, Rhodophyta), from the warm West Coast of India

description: The coast of India is reported to have eight species of bladed Bangiales, five assigned to <i>Porphyra</i> and three to <i>Phycocalidia</i>. Species tend to be seasonal, occurring particularly in the winter and monsoon season. During a reassessment of the diversity of these algae on the Indian coast, a new species of bladed Bangiales, <i>Phycocalidia sukshma</i> M.G.Kavale & M.A.Kazi sp. nov., was discovered and is described from Karwar on the west coast of India. It was collected intertidally during the monsoon season, particularly from the uppermost part of the shore. The species is monostromatic, thin and delicate in texture with 16 spermatia per spermatangium and eight zygotospores per zygotosporangium. The blade margin is undulate with very rare denticulations. Analysis of plastid <i>rbc</i>L and mitochondrial COI-5P resolved <i>Ph. sukshma</i> as a distinct clade, sister to Brazilian and Indian specimens of <i>Ph. vietnamensis</i>. The COI-5P data also revealed that the species known as <i>Porphyra kanyakumariensis</i> Krishnamurthy & Baluswami formed a clade within the genus <i>Phycocalidia</i> and a new combination is made. <i>Phycocalidia kanyakumariensis</i> was collected during the monsoon from the Kanyakumari coast, Tamil Nadu and Mulloor and Leela beach (Kovalam), Kerala. Our work adds to the growing number of warm water species known in this group, indicating the need for further revision of the bladed Bangiales of India and globally.

title: <i>Parakomarekiella sesnandensis</i> gen. et sp. nov. (Nostocales, Cyanobacteria) isolated from the Old Cathedral of Coimbra, Portugal (UNESCO World Heritage Site)

description: In a study that aimed to fingerprint the phototrophic community of the biodeteriorated walls of the Old Cathedral of Coimbra (UNESCO World Heritage Site), an unknown <i>Nostoc</i>/<i>Komarekiella</i>-like cyanobacterium was isolated. We employed a polyphasic approach based on morphological, ecological and phylogenetic analyses of the partial 16S and the whole 16S-23S ITS rRNA regions to characterize this organism. Our strains shared 16S rRNA gene sequence similarity of 99–100% with GenBank-assigned ‘<i>Nostoc</i> sp.’ sequences, and 98% similarity with the genera <i>Goleter, Roholtiella, Aulosira</i> and <i>Komarekiella</i>. Despite being morphologically similar to <i>Komarekiella</i>, phylogenetic analyses placed our strains in a separated genus-level clade, distant from <i>Nostoc</i> sensu stricto and with <i>Komarekiella</i> as the closest taxon. Considering all molecular, phylogenetic and ecological data, we here propose <i>Parakomarekiella sesnandensis</i> F.Soares, V.Ramos & A.Portugal, gen. et sp. nov.

title: A new species of the previously monotypic genus <i>Iningainema</i> (Cyanobacteria, Scytonemataceae) from the Western Ghats, India

description: A novel cyanobacterial species from the genus <i>Iningainema</i> is described according to the International Code of Nomenclature for Algae, Fungi, and Plants. The new species, <i>Iningainema sahyadrensis</i> sp. nov., is recorded from the Western Ghats (Sahyadri mountain range), India. The description is based on morphological features and the phylogenetic analysis of partial 16S rDNA gene. Phylogenetic analysis places <i>I. sahyadrensis</i> in the <i>Iningainema</i> clade, within the family Scytonemataceae. The novel strain formed a strongly supported monophyletic lineage with strains of the type species of <i>Iningainema, I. pulvinus</i>. Laboratory-grown culture and the naturally occurring samples of <i>I. sahyadrensis</i> differed from the type species of the genus (<i>I. pulvinus</i>) by the size of vegetative cells, thickness of sheath, presence of vacuole-like structures in cells and habitat type. Comparison of predicted secondary structures of the partial 16S rRNA molecule of <i>I. sahyadrensis</i> and three clones of <i>I. pulvinus</i> showed a number of evolutionary events in Domain 1 (H8-H10, H17), Domain 2 (H21, H22) and Domain 3 (H33, H34). Amplification of a fragment of the <i>ndaF</i> gene involved in nodularin biosynthesis from <i>I. sahyadrensis</i> did not confirm that it has this genetic determinant, in contrast with <i>I. pulvinus</i>. The recognition and description of this novel species suggests that the cyanobacterial flora of mountain habitats of India has yet to be fully documented.

title: Novel cyanobacterial metabolites, cyanopeptolin 1081 and anabaenopeptin 899, isolated from an enrichment culture dominated by <i>Woronichinia naegeliana</i> (Unger) Elenkin

description: Cyanobacteria synthesize many secondary metabolites of various chemical structures and biological activity and release them into the aquatic environment. Two new oligopeptides belonging to anabaenopeptins and cyanopeptolins were isolated from an enrichment culture dominated by <i>Woronichinia naegeliana</i> (Unger) Elenkin. The application of mass spectrometry and nuclear magnetic resonance spectroscopy allowed determination of their structure and identification of these compounds as cyanopeptolin 1081 and anabaenopeptin 899 with a molecular formula C<sub>52</sub>H<sub>75</sub>N<sub>9</sub>O<sub>16</sub> and C<sub>48</sub>H<sub>65</sub>N<sub>7</sub>O<sub>10</sub>, respectively. The preliminary evaluation of their toxicity was conducted via tests based on crustacean <i>Thamnocephalus platyurus</i>. Although these peptides did not exert acute toxic effects at the concentration up to 40 μg ml<sup>–1</sup>, deterioration of the physiological state of the studied crustaceans, indicated by reduced mobility, was observed. Considering the limited knowledge of cyanopeptide presence in the aquatic environment, it is important to identify and characterize these compounds.

title: <i>Cladophora</i> spp. (Chlorophyta) modulate environment and create a habitat for microalgae in hypersaline waters

description: <i>Cladophora</i> spp. constantly or periodically form floating and benthic mats in Crimean hypersaline lakes and lagoons. In 2017–2018, characteristics of the <i>Cladophora</i> mats and the microalgae on <i>Cladophora</i> filaments were studied employing field research and microscopy. The whole <i>Cladophora</i> mat has a vertical structure, including the upper and lower layers of the floating mat and benthic mat. In total, 50 species of microalgae were found: 40 of them belonged to Bacillariophyta (Bacillariophyceae and Mediophyceae), two to Haptophyta (Coccolithophyceae), four to Miozoa (Dinophyceae), one to Chlorophyta (Zygnematophyceae) and three to Cyanobacteria (Cyanophyceae). Floating layers of the mat differed significantly in species composition from the benthic mat. The total abundance of microalgae and their biomass on <i>Cladophora</i> (per unit area of filaments) varied widely within sampling sites from 3.79 × 10<sup>6</sup> to 5.04 × 10<sup>8</sup> cells m<sup>–2</sup> and 2.6 to 2197.8 mg m<sup>–2</sup>. The total mass of microalgae achieved more than 32% of the mass of <i>Cladophora</i>, averaging 7.7% (standard deviation = 13.3).

title: Geochemistry of shallow sediment including mercury, methylmercury and other constituents in the Cache Creek Settling Basin, Yolo County, California, 2010-16

description: The Cache Creek Settling Basin (CCSB) is a 13.3 km2 leveed basin located at the terminal drainage of the Cache Creek watershed, immediately NE of the town of Woodland (Yolo County), California and approximately 18 km NW of Sacramento, California. The basin was constructed by the U.S. Army Corps of Engineers (completed in 1937 and modified in 1993) for the purpose of trapping suspended sediment transported from the upper Cache Creek watershed during high-flow events, thus preventing sediment from entering the Yolo Bypass, a larger downstream floodwater conveyance and agricultural zone. In addition to trapping suspended sediment, the CCSB also traps sediment-associated mercury (Hg), which is particularly elevated in the upper watershed, owing to natural Hg deposits and associated historic Hg mining areas. The CCSB is a multi-use area containing a number of habitat types that are typical of the California Central Valley region, including: open-water (stream, canal), riparian, floodplain (woody, non-woody), and agriculture (row crop fields) habitats. This dataset includes shallow surface sediment (top 0-2 cm interval) constituent concentration data (primarily) and microbial methylmercury production potential rate data (limited) collected between April 2010 and July 2017 from the above-noted habitats to assess spatial and temporal variations in sediment geochemistry and mercury speciation within the CCSB. The dataset is presented in two sections (child pages): one has the constituent concentration and microbial rate data, and the other includes results of habitat mapping that was conducted within the CCSB for the purpose of data analysis.
