    Description: Formation and evolution of barrier layers (BLs) and associated temperature inversions (TIs) were investigated using a 1-yr time series of oceanic and air–sea surface observations from three moorings deployed in the eastern Pacific fresh pool. BL thickness and TI amplitude showed a seasonality with maxima in boreal summer and autumn when BLs were persistently present. Mixed layer salinity (MLS) and mixed layer temperature (MLT) budgets were constructed to investigate the formation mechanism of BLs and TIs. The MLS budget showed that BLs were initially formed in response to horizontal advection of freshwater in boreal summer and then primarily maintained by precipitation. The MLT budget revealed that penetration of shortwave radiation through the mixed layer base is the dominant contributor to TI formation through subsurface warming. Geostrophic advection is a secondary contributor to TI formation through surface cooling. When the BL exists, the cooling effect from entrainment and the warming effect from detrainment are both significantly reduced. In addition, when the BL is associated with the presence of a TI, entrainment works to warm the mixed layer. The presence of BLs makes the shallower mixed layer more sensitive to surface heat and freshwater fluxes, acting to enhance the formation of TIs that increase the subsurface warming via shortwave penetration.

    Description: La perspectiva de usar las hojas de seiba como suplemento alimentario para el ganado o como abono agrícola requirió determinar la composición química de sus hojas con los siguientes resultados: peso seco 17-34%; cenizas 21-52%; carbono 23-50%; proteínas 8-12%; azúcares reductores 2-13%; fibras 29-40% y grasas 0,5-0,7% con variaciones entre hojas sin epífitas o con ellas, por épocas del año (“lluvia” o “seca”) y profundidad. Las hojas verdes tienen más nitrógeno, proteínas, aminoácidos, azúcares reductores y fibras que las mezcladas y estas más materias secas, cenizas y carbono que las verdes. El peso seco y las proteínas son mayores en “seca” y los azúcares y las fibras en “lluvia”. Entre cero y 5 m de profundidad las proteínas son más abundantes (7%) que a más profundidad (6%) mientras que cenizas y azúcares reductores son, respectivamente, 31 % y 9 % a más de 5 m que a menor profundidad (27 % y 6 %, respectivamente). Entre los 14 aminoácidos encontrados en las hojas verdes (0,22 y 2,65 mg por 100 g de peso seco), siete son esenciales. Calcio, sodio y magnesio son los elementos más abundantes entre los 19 encontrados en las cenizas y entre los tóxicos el cobre es el más abundante (promedio de 0,016%) mientras que otros considerados tóxicos (cobalto, plomo y molibdeno) aparecen solo como trazas (〈 0,0001%). Los factores del entorno con mayor influencia sobre la seiba son luz en el fondo (sobre el crecimiento) y la salinidad (sobre los porcentajes de los componentes químicos).
    Description: The perspective of using turtle grass leaves as a dietary supplement to cattle or as agriculture fertilizer required determining their chemical composition with the following dry weightpercent ranges: dry weight 17-34%; ashes 21-52%; carbon 23-50%; proteins 8-12%; fibers 29-40%; and fats 0.5-0.7% all variable between leaves without epiphytes (green leaves) or mixed leaves, year periods (rain or dry seasons) and depth. Green leaves contain more nitrogen, proteins, amino acids, sugars and fiber, while mixed leaves contain more dry matter, ashes and carbon. Dry weight and proteins are more abundant in the dry season, while sugars and fibers abound more during the wet season. From cero to 5 m proteins are more abundant (7%) than at greater depth (6%), while ashes and sugars are 31% and 9% respectively more abundant at more than 5 meters, that in shallower waters (27% and 6% respectively). Seven of the 14 amino acids found (0.22 y 2.65 mg per 100 g dry weight) were essential. Calcium, sodium and magnesium were the most abundant of the 19 elements found in the ashes (0.016% average) while others consid- ered as toxic (cobalt, lead and molybdenum) appeared only as traces (〈 0.0001%). The environmental factors affecting turtle grass the most were bottom light (on growth) and salinity (on chemical components percentages).

    Description: Martha's Vineyard Coastal Observatory (MVCO) is a leading research and engineering facility operated by Woods Hole Oceanographic Institution. MVCO has been collecting ocean and atmospheric data at 3 sites on and near Martha's Vineyard since 2001. A meteorological mast (met mast) on South Beach in Edgartown, MA has collected atmospheric data since May 31 2001. An Air Sea Interaction Tower (ASIT) has been collecting atmospheric and subsurface oceanic data since August 5, 2004. A seafloor node (12m node) has been collecting oceanic data from the seafloor since June 14, 2001. This dataset encompasses the core data (wind speed and direction, air pressure, temperature and relative humidity, water temperature and salinity, and wave data) that has been collected during this period. To learn more about the facility and see additional data collected during short term deployments, visit the MVCO Website (https://mvco.whoi.edu/).
