To avoid having to change your config, use the 0x prefix when specifying a value in your app.config file.įor example, to specify 12 heaps for GCHeapCount for a. NET Framework, it's interpreted as decimal. NET Framework 4.8+, due to a bug, a value specified without the 0x prefix is interpreted as hexadecimal, but on previous versions of. N is interpreted as a hex value in either formatġ You can specify a value without the 0x prefix for an app.config file setting, but it's not recommended. NET runtime, there are different ways to specify the configuration values. NET runtime, you should still use the COMPlus_ prefix, for example, COMPlus_gcServer.įor different versions of the. If you're using a previous version of the. However, the COMPlus_ prefix will continue to work. NET 6 standardizes on the prefix DOTNET_ instead of COMPlus_. If you're using the environment variables.For hexadecimal values, you can specify them with or without the "0x" prefix. For number values, use decimal notation for settings in the runtimeconfig.json file and hexadecimal notation for environment variable settings.NET process on a machine to use server GC or the same heap hard limit. Because GC is per process, it rarely ever makes sense to set these configurations at the machine level.Settings that can be changed through APIs at run time, such as latency level, are omitted from this page. If you change an environment variable when a process is already running, the change won't be reflected in that process. These configurations are only read by the runtime when the GC is initialized (usually this means during the process startup time).The Save our Seas Act of 2018 amends and reauthorizes the Marine Debris Act to promote international action, authorize cleanup and response actions, and increase coordination among federal agencies on this topic. Local, national, and international efforts are needed to address this environmental problem. This lost or abandoned gear is a major problem because it can continue to capture and kill wildlife, damage sensitive habitats, and even compete with and damage active fishing gear. Some debris, such as derelict fishing gear, can also come from ocean-based sources. Marine debris can also interfere with navigation safety and potentially pose a threat to human health.Īll marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes. Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when it is ingested or they become entangled, and can threaten the habitats they depend on. Our ocean and waterways are polluted with a wide variety of marine debris, ranging from tiny microplastics, smaller than 5 mm, to derelict fishing gear and abandoned vessels. Marine debris is a persistent pollution problem that reaches throughout the entire ocean and Great Lakes. For example, the Harmful Algal Bloom Monitoring System developed by NOAA’s National Centers for Coastal Ocean Science provides information to the public and local authorities to help decide whether beaches need to be closed temporarily to protect public health. These forecasts provide information about how people, economies, and communities may be affected. Using ecological forecasting, NOAA is able to predict changes in ecosystems in response to HABs and other environmental drivers. Many of the marine species that live in these areas either die or, if they are mobile (such as fish), leave the area. When large amounts of algae sink and decompose in the water, the decomposition process consumes oxygen and depletes the supply available to healthy marine life. Excess nutrients entering a body of water, either through natural or human activities, can also result in hypoxia or dead zones. Harmful algal blooms (HABs), also known as “ red tides,” grow rapidly and produce toxic effects that can affect marine life and sometimes even humans. However, if they are too abundant in a body of water, they can stimulate an overgrowth of algae, triggering an event called an algal bloom. For example, the nutrients nitrogen and phosphorus are essential elements for plant growth. Sometimes it is not the type of material, but its concentration that determines whether a substance is a pollutant. Nutrients and algal blooms: Too much of a good thing?
