Refining Fruit-Zone Leaf Removal for Red-Fruited Bordeaux Grape Varieties Grown in a Humid Environment
… limit fungal disease and sunburn incidence, and prevent extreme heating of grapes. The goal of this work was to assess if fruit-zone leaf removal to an uncommonly greater extent, and/or at an earlier phenological stage, would favorably alter yield components or fruit composition in three …

Optimizing grape cluster exposure to increase desirable aroma compounds and decrease disease severity
… Chardonnay. Treatments consisted of control (C), pre-bloom leaf thinning (PB) and two levels of fruit-set leaf thinning (three leaves, PF3 and six leaves, PF6). In an additional project on Cabernet Sauvignon, two levels of hedging (17th node, NH and 12th node, H) were integrated with no leaf …

Observing the seasonal cycle of pCO2 from autonomous pH measurements in the South Atlantic sector of the Southern Ocean
Global climate predictions hinge on our understanding of the global carbon cycle, and in particular, the role of the Southern Ocean (SO). Sea surface measurements across the SO are sparse and subject to temporal, spatial and seasonal biases. These biases arise from the inaccessibility of the SO due …

Quantitative modelling of spatial variability in the north Atlantic spring phytoplankton bloom
… on the development of the spring phytoplankton bloom are investigated using a physically forced model of the annual plankton cycle in the ocean mixed layer. The model is optimised to fit survey data from the eastern North Atlantic, collected over a 1500 x 1500 km area between 39N and 54N, from …

The Impact of Prohexadione-calcium on Grape Vegetative and Reproductive Development and Wine Chemistry
… intervals to Cabernet Sauvignon clusters and pre and post-bloom to Cabernet franc and Chardonnay canopies. Application at E-L stages 21 and 23 decreased Cabernet Sauvignon fruit set whereas application at E-L stages 26, 27, and 29 reduced berry weight without impacting fruit set. Berry weight …

Iron biogeochemistry in the waters surrounding the Crozet Islands, Southern Ocean
… the<br/>Southern Ocean. The annual phytoplankton bloom occurring north of the Crozet Plateau (46°26’S<br/>- 52°18’E) provided a good opportunity to study these phenomena during CROZEX, a<br/>multidisciplinary study performed in austral summers 2004/2005 and 2005/2006. Particular<br/>emphasis has …

Response of Grapes to 2,4-D, Dicamba, and Glyphosate Simulated Drift
… a measureable positive economic effect. With the predicted increase in use of 2,4-D and dicamba, grape growers are concerned about the potential for damage to their vineyards. This research was conducted to better understand the risk associated with this increased use. Grapes were extremely …

Grape yield estimation in commercial vineyards using artificial intelligence, image analysis, and proximal RGB sensing
La estimación precisa del rendimiento de la uva es un reto histórico en viticultura, con implicaciones directas en la gestión del viñedo, la planificación de la vendimia, la logística de bodega y la calidad final del vino. Los métodos tradicionales —muestreo manual y evaluaciones de expertos— son …
