Provides wrong transect with vague/brief justification. Identifies correct transect but very vague and brief answer. Identifies the correct transect but provides very weak observations about the characteristics of the dunes (e.g. morphology of the dunes). Recognizes the time period but no justification or rationale about how the change took place. 1 point Wrong time period, very brief answer with little thought and/or no accuracy. Wrong transect, very brief answer with little thought and/or no accuracy. Indicates correct transect with vague to answer. Wrong transect, very brief answer with little thought and/or no accuracy. Wrong time period and vague/brief answer. 0 points No answer. No answer. No answer. No answer. No answer.
Question 6. Why were the dunes reduced? Provide some explanation about where this sediment may have gone. During which time period did the greatest amount of erosion take place on the island relative to the baseline survey date of February 1, 2008. Explain why you think that this erosion took place. For each survey transect location (1-3) indicate along the transect the most significant erosion take place during the three survey dates. For example did the most amount of erosion on transect 1 take place at the beach face or in the dunes between the first and third survey? Which of the 3 transects shows the greatest amount of net deposition in the dunes during the Alberto recovery time period? 10. Which of the profiles shows the greatest amount of net deposition in the intertidal zone during the Alberto recovery time period? 4 points Identifies and describes why dunes were reduced and provides strong justification for where sediment may have been transported. Identifies when most substantial erosion took place and provides strong justification for why the erosion took place. Correctly discusses erosion of each transect with strong observations. Correctly identifies the transect and provides observations justifying the conclusion. Correctly identifies the transect and provides observations justifying the conclusion. 3 points Identifies and describes why dunes were reduced and provides brief justification for where sediment may have been transported. Identifies when most substantial erosion took place and provides justification for why the erosion took place. Correctly discusses erosion of each transect with moderate observations. Correctly identifies the transect and provides some observations justifying the conclusion. Correctly identifies the transect and provides some moderate observations. 2 points Identifies and describes why dunes were reduced and very weak justification for where sediment may have been transported. Identifies when most substantial erosion took place but provides weak justification for why the erosion took place. Correctly discusses erosion of at least one transect with moderate observations. Correctly identifies the transect and provides weak observations justifying the conclusion. No mention of other transects. Correctly identifies the transect with weak observations and no mention of other transects.
