A. A 1/4-ounce envelope of unflavored gelatin contains 1 tablespoon, which is enough to gel about 2 cups of most clear liquids. Keep in mind that certain foods-figs, ginger root, guava, kiwifruit, papaya, and pineapple-contain an enzyme that prevents gelatin from thickening.
Upwelling in the coastal ocean can be due to a number of factors. In most situations the upwelling is wind driven and its effect on currents, stratification and nutrient supply determined by topographic detail such as water depth and the shape of the coastline.
--Nutrients run off from land, a major reservoirs of P --Light levels are highest just off coastline. Inshore tropical waters have a productivity as much as 10 times higher than offshore because of high nutrients and light. 2. Upwellingzones bring nutrient-rich deep water to the surface, fueling primary productivity Three major mechanisms: Coastal upwelling, equatorial upwelling, island mass effects Coastal upwelling: Winds moving water along the shore result in a curl Right or Left (N or S hemisphere) due to Coriolis effect and Ekman transport.
