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.
Coastal upwelling occurs where Ekman transport moves surface waters away from the coast; surface waters are replaced by water that wells up from below. Where Ekman transport moves surface waters toward the coast, the water piles up and sinks in the process known as downwelling.pwelling and downwelling also occur in the open ocean where winds cause surface waters to diverge (move away) from a region (causing upwelling) or to converge toward some region (causing downwelling). For example, upwelling takes place along much of the equator.
