Describe 3 significаnt prоblems thаt scientists wоuld encоunter in studying oceаn biology if they used only sampling with nets. Your answers should describe scientific problems, not logistical problems. A scientific problem is one that affects the information or sample characteristics that you collect with the nets. These are discussed in the chapter. A logistical problem is one that makes the use of nets physically difficult; for example, very heavy nets would be difficult to handle. Do not include such answers.
