When I downloaded the BBS route shape file (apologies for not linking, I’m not sure if it’s publicly available) I had some work to do. I wrote down the steps I used in cleaning up the layer, and then splitting into fifths. One line per route. Great! set aside. (Still a note of caution, some […]

I made a series of posts of how to get BBS data and import it into R, as well as an example of predictor data for a model, and how to get that into R. Here I’ll collect it all into a step-by-step by linking to those posts. How to get BBS data Importing BBS […]

BBS data is essentially aggregated point count data, that in its raw form has a row for each species observed at each route in each year. This means that if a species is not recorded in a  given year, it just doesn’t have a record. I need to add those zeros back in, such that if […]

I have used remote sensing products in my BBS analyses in various capacities, but it all boils down essentially to the same spatial statistics. I wrote a post about how to download and process MODIS VCF images. At the end of that post, you have a folder of TIFF images of your variable of interest at […]

I found this gem while poking around Flood Bay this afternoon! It’s a fortification and a floater agate, which is mostly micro-crystalline quartz. Last weekend, my I taught my boyfriend about agate hunting, and we found a number of them. There’s a corner of this one (left) that’s broken to reveal very fine banding, but […]

I’ve been keeping odd-looking rocks I don’t know what to make of to ID later. This one looks like brecciated jasper(?) that got cemented within quartz. There is some banding around the broken pieces.

Until I figure out how to pin posts in a tag(?) here’s where my posts have gotten us so far with a starter script for BBS data. Start with the data tutorial before getting to this step to download North American BBS data. This script imports your data into R… rm(list = ls()) setwd(“”) library(foreign) […]

My significant other, in getting his M.S. research ready for publication, introduced me to multilevel modeling, and we worked through a reanalysis together. Now, I’m also interested to apply this framework to my 2nd dissertation chapter before publishing, so I can model cohesive community response while still extracting species’ responses. The following code block is copied […]

I cleared up the “ophitic basalt” debate, at least to my satisfaction, this evening. I went to a beach listed in my book to have a good amount of ophitic basalt, and it looks quite different to me than what I would identify as diabase (I found some of that there too).

Most of the rocks at Flood Bay are basalt. I’m still confused about how to differentiate ophitic basalt from diabase, though. One of my books draws a distinction, but another doesn’t. I read into it online, but I’ll have to keep studying in the field!
