    Description: Photosynthetic production of organic matter by microscopic oceanic phytoplankton fuels ocean ecosystems and contributes roughly half of the Earth's net primary production. For 13 years, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) mission provided the first consistent, synoptic observations of global ocean ecosystems. Changes in the surface chlorophyll concentration, the primary biological property retrieved from SeaWiFS, have traditionally been used as a metric for phytoplankton abundance and its distribution largely reflects patterns in vertical nutrient transport. On regional to global scales, chlorophyll concentrations covary with sea surface temperature (SST) because SST changes reflect light and nutrient conditions. However, the ocean may be too complex to be well characterized using a single index such as the chlorophyll concentration. A semi-analytical bio-optical algorithm is used to help interpret regional to global SeaWiFS chlorophyll observations from using three independent, well-validated ocean color data products; the chlorophyll a concentration, absorption by CDM and particulate backscattering. First, we show that observed long-term, global-scale trends in standard chlorophyll retrievals are likely compromised by coincident changes in CDM. Second, we partition the chlorophyll signal into a component due to phytoplankton biomass changes and a component caused by physiological adjustments in intracellular chlorophyll concentrations to changes in mixed layer light levels. We show that biomass changes dominate chlorophyll signals for the high latitude seas and where persistent vertical upwelling is known to occur, while physiological processes dominate chlorophyll variability over much of the tropical and subtropical oceans. The SeaWiFS data set demonstrates complexity in the interpretation of changes in regional to global phytoplankton distributions and illustrates limitations for the assessment of phytoplankton dynamics using chlorophyll retrievals alone.

    The influence of sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms in the Chukchi Sea (2015)

    Description: © The Author(s), 2015. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Deep Sea Research Part II: Topical Studies in Oceanography 118 (2015): 122-135, doi:10.1016/j.dsr2.2015.02.008.
    Description: A coupled biophysical model is used to examine the impact of changes in sea ice and snow cover and nutrient availability on the formation of massive under-ice phytoplankton blooms (MUPBs) in the Chukchi Sea of the Arctic Ocean over the period 1988–2013. The model is able to reproduce the basic features of the ICESCAPE (Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment) observed MUPB during July 2011. The simulated MUPBs occur every year during 1988–2013, mainly in between mid-June and mid-July. While the simulated under-ice blooms of moderate magnitude are widespread in the Chukchi Sea, MUPBs are less so. On average, the area fraction of MUPBs in the ice-covered areas of the Chukchi Sea during June and July is about 8%, which has been increasing at a rate of 2% yr–1 over 1988–2013. The simulated increase in the area fraction as well as primary productivity and chlorophyll a biomass is linked to an increase in light availability, in response to a decrease in sea ice and snow cover, and an increase in nutrient availability in the upper 100 m of the ocean, in conjunction with an intensification of ocean circulation. Simulated MUPBs are temporally sporadic and spatially patchy because of strong spatiotemporal variations of light and nutrient availability. However, as observed during ICESCAPE, there is a high likelihood that MUPBs may form at the shelf break, where the model simulates enhanced nutrient concentration that is seldom depleted between mid-June and mid-July because of generally robust shelf-break upwelling and other dynamic ocean processes. The occurrence of MUPBs at the shelf break is more frequent in the past decade than in the earlier period because of elevated light availability there. It may be even more frequent in the future if the sea ice and snow cover continues to decline such that light is more available at the shelf break to further boost the formation of MUPBs there.

    Bio-optical discrimination of diatoms from other phytoplankton in the surface ocean: Evaluation and refinement of a model for the Northwest Atlantic (2018)
    Elsevier
    Details
    Publication Date: 2022-05-25
    Description: © The Author(s), 2018. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Remote Sensing of Environment 217 (2018): 126-143, doi:10.1016/j.rse.2018.08.010.
    Description: Diatoms dominate global silica production and export production in the ocean; they form the base of productive food webs and fisheries. Thus, a remote sensing algorithm to identify diatoms has great potential to describe ecological and biogeochemical trends and fluctuations in the surface ocean. Despite the importance of detecting diatoms from remote sensing and the demand for reliable methods of diatom identification, there has not been a systematic evaluation of algorithms that are being applied to this end. The efficacy of these models remains difficult to constrain in part due to limited datasets for validation. In this study, we test a bio-optical algorithm developed by Sathyendranath et al. (2004) to identify diatom dominance from the relationship between ratios of remote sensing reflectance and chlorophyll concentration. We evaluate and refine the original model with data collected at the Martha's Vineyard Coastal Observatory (MVCO), a near-shore location on the New England shelf. We then validated the refined model with data collected in Harpswell Sound, Maine, a site with greater optical complexity than MVCO. At both sites, despite relatively large changes in diatom fraction (0.8–82% of chlorophyll concentration), the magnitude of variability in optical properties due to the dominance or non-dominance of diatoms is less than the variability induced by other absorbing and scattering constituents of the water. While the original model performance was improved through successive re-parameterizations and re-formulations of the absorption and backscattering coefficients, we show that even a model originally parameterized for the Northwest Atlantic and re-parameterized for sites such as MVCO and Harpswell Sound performs poorly in discriminating diatom-dominance from optical properties.

    Description: Data on development rate, composition and structure of the aquatic food organisms in the Lysyi Liman L. (Stavropol Krai, Russia) are presented. Using the indices, describing the processes of biological production, possible increase in fish productivity by introducing Far Eastern fish species and Eastern carp was estimated. The amount of food resources in the Lysyi Liman L. under conditions of their rational exploitation can allow to increase fisheries productivity of this water body by 224 kg/ha. Taking into account the natural mortality percentage, the rates of stocking the lake with fingerlings (yearlings) of phytophagous species and Eastern carp for rational exploitation of the water body's food resources were calculated.

    Description: Лаборатория технологии и механизации обработки рыбы начала свою деятельность в АзЧерНИРО в 1958 г., после завершения строительства нового здания института в Керчи по ул. Свердлова, 2. Следует отметить, что технологические исследования к тому времени велись в Доно-Кубанском отделении АзЧерНИРО (г. Ростов-на-Дону). Первой заведующей лабораторией стала Г.К. Ковальчук – высококвалифицированный специалист, которая организовала и сплотила коллектив технологов, определила основные направления научной деятельности. Исследования, проводимые лабораторией, были связаны прежде всего с сохранением свежести азово-черноморских рыб, определением сроков хранения рыбы-сырца и охлажденной рыбы на судах. Для Азово-Черноморского бассейна, где в летний период температура воздуха достигает 30 °С и выше, сохранение выловленной рыбы всегда имеет особо важное значение. В конце 1950-х гг. предлагалось решить проблему сохранения рыбы-сырца путем применения антибиотиков тетрациклиновой группы (биомицина). Сейчас применение антибиотиков при производстве пищевой продукции вызывает у нас неприятие, тогда же это было одно из актуальных направлений исследований, проводимых на всех рыбохозяйственных бассейнах. С 1956 г. в Канаде было официально разрешено обрабатывать рыбу льдом, содержащим биомицин. В 1959 г. в Ленинграде был проведен Всесоюзный коллоквиум по применению антибиотиков в рыбной промышленности, разработана методика проведения исследований. Технологической лабораторией АзЧерНИРО была подтверждена возможность использования биомицина для бычка и ставриды; для хамсы применение биомицина было нецелесообразным, поскольку при ее хранении при температуре от 3 до 5 °С процессы окисления протекали быстрее, чем бактериальная порча. С образованием лаборатории была начата работа по технологическому нормированию, которая проводилась совместно с производственными лабораториями. Требовался пересмотр действующих бассейновых норм, поскольку они не соответствовали современному уровню технологии и технической оснащенности предприятий. Технологические исследования неразрывно связаны со стандартизацией. Уже в 1959 г. Н.И. Горемыкиной были начаты работы по стандартизации. По заказу Госплана УССР разрабатывались республиканские технические условия на продукцию, требования к которой не были установлены в общесоюзных стандартах. Это были технические условия на мелкую рыбу-сырец, охлажденную, мороженую, холодного и горячего копчения; бычок охлажденный, мороженый и горячего копчения; на соленую продукцию, варено-мороженые раки, консервы из пеламиды, ставриды и др. При разработке нормативных документов в производственных условиях проверялись предложения от рыбопромышленных предприятий.

    Description: A set of experiments on a specific testing unit with simulation of the mussel collectors' movement in the water equaling the one under conditions of a storm is described. Comparative analysis with the nearby stable collectors with mussels was made. Three modes of fixing collectors to the supporting parts of the available marine constructions with estimation of the negative impact of waves on mussels were investigated. The experiment results allowed to improve the engineering design for three types of the marine constructions: 1) collector-carrier of the saw-shape; 2) U-shape linear comb construction; 3) construction of the vertical candle shape.
    Description: Описан комплекс экспериментальных работ на специальном стенде с имитацией перемещения коллекторов с мидиями в воде, как при штормовом волнении. Определяли временной порог появления негативного влияния колебаний на физиологическое состояние моллюсков. Сравнение проводили с моллюсками, находящимися на коллекторах в покое и расположенными в воде рядом. Исследовали три способа подвешивания коллекторов к несущим частям известных морских сооружений с определением степени отрицательного воздействия волновых колебаний на мидии. Результаты экспериментов позволили оптимизировать конструкции трех типов морских сооружений: 1) коллектора-носителя пилообразного (КНП); 2) сооружения П-образного, линейного, гребенчатого (СГЛ); 3) сооружений типа вертикальная свеча (ВС).

    Description: Average values of phytoplankton abundance and biomass in the Taganrog Bay area (Azov Sea, Russia) in February-March of 2016 made up 9.18-16.013 million cells/l and 901-2,621 mg/m3. The values of quantitative development of phytoplankton in the Don R. delta during the same time period (657-184 thousand cells/l and 154-127 mg/m3) were lower than the ones in the Taganrog Bay in 14-87 and 6-20 times, respectively. Great amounts of algae in the Don R. delta in April 2016 (73 thousand cells/l and 248 mg/m3) equaled winter values. Invasion of allochthonic species of diatoms Pseudosolenia calcar-avis into the Taganrog Bay area in February-March 2016, can be related to the increase in salinity, which has been observed in this part of the sea for the last years.
    Description: Средние величины численности и биомассы фитопланктона на акватории Таганрогского залива в феврале-марте 2016 г. составили 9,18-16,013 млн. кл./л и 901-2621 мг/м3. В то же время величины количественного развития фитопланктона в дельте и русле р. Дон (657-184 тыс. кл./л и 154-127 мг/м3) уступали, соответственно, в 14-87 и 6-20 раз значениям Таганрогского залива. Обилие водорослей в дельте р. Дон в апреле 2016 г. (573 тыс. кл./л и 248 мг/м3) было на уровне зимних величин. Проникновение аллохтонного вида диатомовых водорослей Pseudosolenia calcar-avis в акваторию Таганрогского залива в феврале-марте 2016 г., вероятно, связано с наблюдавшимся в последние годы повышением солености этого района моря.

This method offers the prospect for production of balanced complete feeds for poultry, hogs, cattle, sheep, furbearing animals, rabbits, nutrias, horses, non-livestock animals (cats, dogs), as well as for the production of both concentrated and high-protein feeds for fish. The recommended mode of raw fish fermentolysis for subsequent shaping of smooth pellets and their effective chipping with a knife is established: with the dose of enzymatic agent protosubtilin G3x being 0.5 % in relation to the fish weight, duration – 4 hours, and temperature – 54 °С, duty of water curve (hydromodulus) is not applied. It is shown that, for the adopted modes, there is no need to add sodium pyrosulphite as a preserving agent to ensure microbiological stability of fermentolysis process.
    Description: Показана возможность использования в качестве источника полноценного белка в технологии приготовления кормов ферментированной целиком (без разделки) мелкой азово-черноморской рыбы – шпрота, хамсы, тюльки. Данный способ обеспечивает возможность производства полнорационных кормов для сельскохозяйственной птицы, свиней, крупного рогатого скота, овец, пушных зверей, кроликов, нутрий, лошадей, непродуктивных животных (кошек, собак), а также кормов-концентратов и высокобелковых кормов для рыбы. Установлен рекомендуемый режим ферментолиза рыбного сырья для последующего формирования ровных гранул и эффективного обламывания их ножом: доза ферментного препарата протосубтилин Г3х – 0,5 % к массе рыбы, продолжительность 4 ч, температура 54 °С, без использования гидромодуля. Показано, что для принятых режимов отсутствует необходимость в добавлении пиросульфита натрия в качестве консерванта для обеспечения микробиологической стабильности процесса ферментолиза.

    Description: Arranging organisms into functional groups aids ecological research by grouping organisms (irrespective of phylogenetic origin) that interact with environmental factors in similar ways. Planktonic protists traditionally have been split between photoautotrophic “phytoplankton” and phagotrophic “microzooplankton”. However, there is a growing recognition of the importance of mixotrophy in euphotic aquatic systems, where many protists often combine photoautotrophic and phagotrophic modes of nutrition. Such organisms do not align with the traditional dichotomy of phytoplankton and microzooplankton. To reflect this understanding, we propose a new functional grouping of planktonic protists in an eco-physiological context: (i) phagoheterotrophs lacking phototrophic capacity, (ii) photoautotrophs lacking phagotrophic capacity, (iii) constitutive mixotrophs (CMs) as phagotrophs with an inherent capacity for phototrophy, and (iv) non-constitutive mixotrophs (NCMs) that acquire their phototrophic capacity by ingesting specific (SNCM) or general non-specific (GNCM) prey. For the first time, we incorporate these functional groups within a foodweb structure and show, using model outputs, that there is scope for significant changes in trophic dynamics depending on the protist functional type description. Accordingly, to better reflect the role of mixotrophy, we recommend that as important tools for explanatory and predictive research, aquatic food-web and biogeochemical models need to redefine the protist groups within their frameworks.
