Spatial and temporal patterns in Hawai'i's intertidal: decadal changes in benthic community composition

(2020)

Spatially broad and long-term monitoring studies are lacking in tropical intertidal systems yet are necessary to test predictions regarding community assembly. To fill this gap, we examined spatial and decadal temporal patterns in benthic community structure at rocky intertidal sites along the main islands of Hawai‘i. Quantitative community surveys done in 2017 across nine sites and five islands showed that organismal composition differed by site, substrate type, and island. Secondly, we leveraged an earlier dataset collected using the same methods and analyzed intertidal communities at five sites on three Hawaiian islands for temporal changes in organismal abundance and composition from 2006 and 2007 vs. 2016 and 2017. Overall community structure differed significantly across years and decades. Most decadal differences were site specific, such as the fivefold increase in turf algae at one site. Crustose coralline algae and Turbinaria ornata increased significantly across five sites; both are physically resilient algae and similar increases in their abundances have been observed in tropical systems worldwide. This increase in physically resilient macroalgal species is potentially caused by global drivers, such as rising temperatures and changing land uses. In conclusion, there is evidence that both local and regional factors contribute to structuring tropical intertidal communities.

SPICE Mooring Data Report: Description and Quality Control

(2017)

The Solomon Sea is an important region for western Pacific water mass circulation, serving as the pathway that connects subtropical and equatorial waters. To observe this water mass transport, nine moorings were deployed in the exit channels of the Solomon Sea as an observational component of the Southwest Pacific Ocean Circulation and Climate Experiment (SPICE). This report details the deployment and recovery of the moored velocity, temperature, salinity, and pressure observations and the subsequent quality control procedures applied to the recovered observations. A summary of the quality controlled data is also given for each mooring.

Catalog of Otoliths of Select Fishes from the California Current System

(2014)

This catalog contains images and features of sagittal otoliths from 47 species belonging to 17 families of fish found in the California Current System. We focus primarily on mesopelagic species, which are ecologically important yet are less studied than other species. For each sagitta, two images are presented, one with the sulcus up and another with the sulcus down. The linear relationship between standard length (SL) of a fish and major axis length (MAL) of its sagitta is presented for 24 species. Significant variability in SL is explained by MAL for 22 of the 24 species (n =5-61, R2 > 0.61, p < 0.05). Collection data and geometric shape features of all otoliths are also presented in tabular format. Our guide will assist researchers in the identification of sagittal otoliths of unknown origin and to estimate fish length from sagittal otolith size.
