    "title": "'Hot spot' analysis of red snapper (Lutjanus campechanus) commercial vertical line data recorded by the Gulf of Mexico Reef Fish Observer Program, 2007 - 2013.",
    "description": "Getis-Ord Gi analysis of kept and discarded red snapper, Lutjanus campechanus, capture from observations recorded by NOAA Fisheries Service Galveston Laboratory Gulf of Mexico Reef Fish Observer Program 2007-2013 (28,087 sets made during 731 trips). Average capture summarized by 15-minute grid blocks. The hot spot, or Getis-Ord Gi statistic, is used to detect clusters of high or low catch per unit effort (CPUE) values. In ArcGIS, the hot spot tool looks at the value of each feature in relation to the values for its neighboring features. A statistically significant Z-score results if the sum for a feature and its neighbors, when compared proportionally to the sum of all features, is different from what is expected. If a feature is surrounded by neighbors with similarly high (or low) values, then it is part of a statistically significant hot (or cold) spot. Data are categorized by Z-scores, a measure of standard deviation. With a 95% confidence level, or p-value of 0.05, the critical Z-score values are -1.96 and +1.96 standard deviations; and -2.58 and +2.58 for a 99% confidence level, or p-value of 0.01. Blocks with less than 3 vessels were included in analysis, but removed before distribution for confidentiality purposes.",
