Question

name braylin robey class 5th date 10/1/23 central case the gulf of mexicos dead zone the changing size of the dead zone the hypoxic zone, or area of low oxygen, in the gulf of mexico varies in size from year to year. the national oceanic and atmospheric administration (noaa) supports research that measures and monitors the size of the dead zone in the gulf of mexico annually. the graph below shows the results of such research. this data help scientists determine which factors cause the dead zone to grow or shrink. most analyses show that the biggest factor in the size of the dead zone is the amount of nitrogen and other nutrients that reaches the gulf from the mississippi river watershed each spring. the u.s. geological survey (usgs) measures the amount of nitrogen that reaches the gulf each year and correlates that amount with the size of the dead zone. its scientists have found that when the amount of nitrogen increases, the size of the dead zone increases. currently there are several plans to reduce the size of the dead zone to an acceptable level, indicated by the action plan goal line on the graph. although the dead zone is fueled by nitrogen runoff, scientists know that short - term weather patterns can also have an effect on the size of the hypoxic region. for example, when the region experiences periods of extreme weather, the heavy winds and wave activity cause more oxygen to infuse into the waters—counteracting the effects of nitrogen runoff and slowing the growth of the dead zone. scientists feel it is important to track and account for these short - term effects, in the model they are developing to study the dead zone as well. this way, they will be able to establish a link between fertilizer runoff and size of the dead zone without having the data skewed due to weather effects. establishing a good model with all the data available can help achieve the goals needed to reach acceptable levels. with the dead zone reduced in size, the gulf of mexico can then be restored for fishing and recreation. part 1: analyze the information use the provided text, the changing size of the dead zone, to answer the following questions. 1. which two government agencies are mentioned as studying the dead zone, and what does each one measure or support?

Explanation:

The text mentions two government - agencies. NOAA supports research to measure and monitor the size of the dead zone. USGS measures the amount of nitrogen reaching the Gulf and correlates it with the size of the dead zone.

Answer:

1. The National Oceanic and Atmospheric Administration (NOAA) supports research that measures and monitors the size of the dead zone in the Gulf of Mexico annually. The U.S. Geological Survey (USGS) measures the amount of nitrogen that reaches the Gulf each year and correlates that amount with the size of the dead zone.
