Carta de restauração dos fósseis

A Itália é um país com forte tradição no campo da restauração. Não surpreende, portanto, que a Carta de Restauração dos Fósseis tenha nascido em contexto italiano. O documento, publicado em 1998, organiza e sistematiza informações sobre cada atividade que possa influenciar na longevidade do fóssil, desde a escavação até o momento de guarda em uma instituição. Apesar de muitos dos pontos abordados serem intrínsecos do “fazer paleontologia”, algumas questões nos parecem relevantes para profissionais que queiram tratar de fósseis. Algo importante a enfatizar, por exemplo, é a inclusão de informações de campo, de preparação e conservação na documentação do registro na coleção científica – dados já apontados para uma documentação museológica. Outro ponto importante a destacar é a necessidade das instituições de prover laboratórios de preparação, restauração e conservação para os vários objetos de pesquisa, com profissionais qualificados nas diversas áreas de conhecimento necessárias para estas atividades. Infelizmente, isso ocorre pontualmente em certas instituições. Acreditamos que as normas de restauração e de conservação de fósseis, normalmente dispersas em várias bibliografias, foram habilmente sintetizadas na presente carta, favorecendo o conhecimento dos princípios básicos dos critérios de base e normas a serem seguidas para a coleta, preparação, restauração e conservação de material fóssil. E, ainda que a realidade italiana seja diversa da brasileira em muitos aspectos, as boas práticas indicadas no texto têm o potencial de servir de norte para políticas de gestão de coleções paleontológicas. Por fim, agradecemos ao Dr. Vittorio Borselli, coordenador da presente Carta, por conceder a autorização para tradução do documento, e assim, proporcionar sua difusão abrangente entre os profissionais que trabalham com a curadoria de material paleontológico no Brasil

The Copernicus Marine Service ocean forecasting system for the Mediterranean Sea

The Mediterranean Monitoring and Forecasting Center (MED-MFC) is part of the Copernicus Marine Environment and Monitoring Service (CMEMS) and provides regular and systematic information on the time-evolving Mediterranean Sea physical (including waves) and biogeochemical state. The systems consist of 3 components: 1) Med-Physics, a numerical ocean prediction systems, based on NEMO model, that operationally produces analyses, reanalysis and short term forecasts of the main physical parameters; 2) Med-Biogeochemistry, a biogeochemical analysis, reanalysis and forecasting system based on the Biogeochemical Flux Model (BFM) which provides information on chlorophyll, phosphate, nitrate, primary productivity, oxygen, phytoplankton biomass, pH and pCO2; 3) Med-Waves based on WAM model and providing analysis, forecast and reanalysis products for waves. The systems have been recently upgraded at a resolution of 1/24 degree in the horizontal and 141 vertical levels. The Med-Physics analysis and forecasting system is composed by the hydrodynamic model NEMO 2-way coupled with the third-generation wave model WaveWatchIII and forced by ECMWF atmospheric fields. The model solutions are corrected by the 3DVAR data assimilation system (3D variational scheme adapted to the oceanic assimilation problem) with a daily assimilation cycle of sea level anomaly and vertical profiles of temperature and salinity. The model has a non-linear explicit free surface and it is forced by surface pressure, interactive heat, momentum and water fluxes at the air-sea interface. The biogeochemical analysis and forecasts are produced by means of the MedBFM v2.1 modeling system (i.e. the physical-biogeochemical OGSTM-BFM model coupled with the 3DVARBIO assimilation scheme) forced by the outputs of the Med-Physics product. Seven days of analysis/hindcast and ten days of forecast are bi-weekly produced on Wednesday and on Saturday, with the assimilation of surface chlorophyll concentration from satellite observations. In-situ data are mainly used to estimate model uncertainty at different spatial scales. The Med-Waves modelling system is based on the WAM Cycle 4.5.4 wave model code. It consists of a wave model grid covering the Mediterranean Sea at a 1/24° horizontal resolution, nested to a North Atlantic grid at a 1/6° resolution. The system is forced by ECMWF winds at 1/8°. Refraction due to surface currents is accounted by the system which assimilates altimeter along-track significant wave height observations. On a daily basis, it provides 1-day analysis and 5-day forecast hourly wave parameters. Currently, wave buoy observations of significant wave height and mean wave period along with satellite observations are used to calibrate and validate the Med-waves modelling system.PublishedHalifax, Nova Scotia, Canada4A.

Copernicus Ocean State Report, issue 6

The 6th issue of the Copernicus OSR incorporates a large range of topics for the blue, white and green ocean for all European regional seas, and the global ocean over 1993–2020 with a special focus on 2020

Biogeochemical Flux Model (BFM) for FABM

<p>The open source, Fortran-based Framework for Aquatic Biogeochemical Models (FABM, Bruggeman and Bolding 2014) enables the development of complex BGC models in the form of stand-alone, process-specific modules. These are combined at runtime through coupling links to form a customized BGC/ecosystem model.</p><p>The development of BFM for FABM is based on a modular approach, in particular, different subroutines and FABM models are associated with the different functional plankton types (PFTs, eg, phytoplankton, zooplankton) and chemical processes (eg, light, denitrification) included in the ecosystem model.</p><p>The coupled FABM-BFM is developed starting from the original style and structure of the official BFM code. Therefore, although the code implementation involved a redesign of the BFM code into a FABM-compliant modular structure, the core of the overall conceptual model of BFM remains intact.</p&gt

Observational datasets for validation of Mediterranean Biogeochemical Copernicus Modelling System, period 2018-2020

Datasets used for the validation of the biogeochemical component of the Mediterranean Analysis and Forecast center of the EU Copernicus Marine Service for the period 2018-2020. The list of datasets includes: 1) the Delay Mode Satellite chlorophyll from https://data.marine.copernicus.eu/product/OCEANCOLOUR_MED_BGC_L3_NRT_009_141/description after interpolation to the 1/24° horizontal resolution, weekly averages and quality check with internal climatology 2) the BGC-Argo float profiles of nitrate, chlorophyll and oxygen from Coriolis DAC (ftp://ftp.ifremer.fr/ifremer/argo; https://doi.org/10.17882/42182#76230) after an internal quality check procedure which is described in Salon et al., 2019. 3) the climatological profiles for 16 subbasins of nitrate, phosphate, silicate, oxygen, DIC, alkalinity, pCO2 and pH computed from the Emodnet 2018 data collection and additional scientific datasets as described in Salon et al., 2019.
