Drifter position data from the eastern coast of Brazil during the project Mission Microbiomes with the RV Tara
No full textDuring the project Mission Microbiomes with the RV Tara (August to September 2021) 43 Lagrangian drifters were deployed off the eastern coast of Brazil to monitor the surface flow. The drifters were designed and built at Hereon to follow the upper surface flow (upper ~ 50 cm). These Hereon drifter consist of a 20 cm x 7.5 cm long tube, with a floatation ring at the top. Furthermore, a drogue of 35 cm in both length and diameter is attached, via a flexible cord, in a distance of 20 cm to the tube. When deployed about 5 cm protrude from the water surface, resulting in a ratio of drag area in to drag area outside the water of 21. The tube contains a battery pack and an electronic board, which acquires and reports the GPS position every 5 minutes via a global satellite network in near real time. Table 1 in the attached document summarizes for all deployed Hereon Drifters their deployment time as well as operation time and total covered distance

Martin est en colère by J. Theobald & K. Viala
No full textTheobald, Joeseph and Kévin Viala. Martin est en colère. Toronto: Éditions Scholastic, 2014. Print.This picture book tells a humorous story about a sheep that gets angry very easily when he does not get what he wants. His anger turns him into a nasty and ferocious monster. In the end, he becomes stranded and realizes that it’s not so fun to get mad.I really enjoyed this silly and funny book. I found the pictures to be amusing, colourful and very expressive. The visuals were large and really demonstrated what was happening in the book, to the point where words were not necessarily required to understand the story. The pictures made the story funny, especially when the main character becomes a monster.I loved the fact that all the characters in this book were animals. Animal books are often a great fit for younger students since the character is more easily relatable and does not imply any cultural or ethnic barriers.When it came to the writing, the author used language that was not too complicated or wordy. I especially like this for those students in French Immersion programs since the vocabulary is not too advanced for native English speakers learning French. The text and the images make this a great read for younger students at an intermediate level in the French language.What struck me the most about this book is the open ending. This ending leaves the reader wondering if Martin will make a change in his action this time or whether he will fall back on old habits. Overall this was a feel good, easy to understand and humorous picture book that displays a great message about looking for solutions instead of losing your cool.Highly recommended: 4 out of 4 starsReviewer: Vanessa PesantVanessa Pesant is a grade 2 French immersion teacher in Beaumont.

Methodology used on board to prepare samples from the Tara Oceans Expedition (2009-2013)
No full textThe Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides methodological context about the sampling and on-board-preparation of samples during the Tara Oceans Expedition (2009-2013). For each sample, we provide details about the standard protocols (i.e. Sample Method) as well as deviations from these protocols (i.e. Sample Comment). We also provide URLs to related data, sampling logsheets, campaign summary reports, oceanographic reports, and step-by-step protocols

Environmental context of all samples from the Tara Oceans Expedition (2009-2013), about pigment concentrations (HPLC) in the targeted environmental feature
No full textThe Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about pigment concentrations in the targeted environmental feature. Pigment concentrations were measured by High Pressure Liquid Chromatography (HPLC) on water samples. For each parameter we provide six statistics about all observations that are considered adequate to characterise the targeted environmental feature: number of observations, minimum, first quartile (25 percentile), median, third quartile (75 percentile), and maximum values. Observations were considered adequate if they met the following criteria: <100 km from the sampling location, <2 days from the sampling date/time, and within 10 m of the sampling depth. We also provide the computed distance and date/time lags that were assessed against these criteria. No environmental context is provided when one of these criteria was not met
Environmental context of all samples from the Tara Oceans Expedition (2009-2013), about carbonate chemistry in the targeted environmental feature

Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides environmental context to all samples from the Tara Oceans Expedition (2009-2013), about carbonate chemistry in the targeted environmental feature. Total alkalinity (AT) and total carbon (CT) were measured potentiometrically (Edmond 1970), and other carbonate chemistry parameters (pH on total scale, CO2, pCO2, fCO2, HCO3, CO3, OmegaAragonite and OmegaCalcite) were calculated using seacarb (Nisumaa et al. 2010). For each parameter we provide six statistics about all observations that are considered adequate to characterise the targeted environmental feature: number of observations, minimum, first quartile (25 percentile), median, third quartile (75 percentile), and maximum values. Observations were considered adequate if they met the following criteria: <100 km from the sampling location, <2 days from the sampling date/time, and within 10 m of the sampling depth. We also provide the computed distance and date/time lags that were assessed against these criteria. No environmental context is provided when one of these criteria was not met
Global data product of chlorophyll a concentration and phytoplankton community composition (microphytoplankton, nanophytoplankton and picophytoplankton) computed from in situ fluorescence profiles
No full textIn vivo chlorophyll a fluorescence, a proxy of chlorophyll a concentration, is one of the most frequently measured biogeochemical property in the ocean. Thousands of profiles are available from historical databases and the integration of fluorescence sensors to autonomous platforms led to a significant increase of chlorophyll fluorescence profiles acquisition. To date, benefits of such numerous data available have not yet been included in global analysis. A total of 268,184 raw chlorophyll fluorescence profiles were collected and subjected to a 10-steps quality control procedure (see supplementary literature publication).
The present data product was generated from the remaining 48,600 chlorophyll fluorescence profiles. These were inter-calibrated, converted to total chlorophyll a concentration and phytoplankton community composition (i.e. microphytoplankton, nanophytoplankton and picophytoplankton) using the FLAVOR method (see further details). The data span a time period of 1958-2015, with observations from all oceanic basins and all seasons, and with depths ranging from the surface to a median sampling maximum depth of around 700m.
The present data product was obtained by modelling phytoplankton biomass and composition from in situ fluorescence profiles and therefore, individual profiles should NOT BE USED as discrete observations. The correct use of the present data product is to investigate regional or temporal trends, for example to improve the open ocean climatologies of chlorophyll a concentration.
This data product is intended as a living data set, with the expectation to retrieve and model additional in situ chlorophyll fluorescence profiles, especially from autonomous acquisition platforms
