1. Digitizing North American Fishes

   In the past decade, the ability to construct digital models of natural history specimens has become faster, cheaper, and easier for researchers. This in part has led to the modern movement to cre- ate models of representatives of all vertebrate species and make these data freely available to other researchers and the general public. The openVertebrate project (or “oVert”) is leading this charge by using micro computed tomographic (μCT) scanners at universities across the United States to synchronously tackle this ambitious initiative. But what happens to a specimen in a museum before a digital model of that specimen is published on the internet? Here we provide a window into some of the steps involved in this process and focus on what is involved in scanning specimens of fishes.

   Abstract Winter surface air temperature (SAT) over North America exhibits pronounced variability on subseasonal, interannual, decadal, and interdecadal time scales. Here, reanalysis data from 1950–2017 are analyzed to investigate the atmospheric and surface ocean conditions associated with its subseasonal to interannual variability. Detrended daily SAT data reveal a known warm west/cold east (WWCE) dipole over midlatitude North America and a cold north/warm south (CNWS) dipole over eastern North America. It is found that while the North Pacific blocking (PB) is important for the WWCE and CNWS dipoles, they also depend on the phase of the North Atlantic Oscillation (NAO). When a negative-phase NAO (NAO − ) coincides with PB, the WWCE dipole is enhanced (compared with the PB alone case) and it also leads to a warm north/cold south dipole anomaly in eastern North America; but when PB occurs with a positive-phase NAO (NAO + ), the WWCE dipole weakens and the CNWS dipole is enhanced. The PB events concurrent with the NAO − (NAO + ) and SAT WWCE (CNWS) dipole are favored by the Pacific El Niño–like (La Niña–like) sea surface temperature mode and the positive (negative) North Pacific mode. The PB-NAO + has a larger component projecting onto the SAT WWCE dipole during the La Niña winter than during the El Niño winter because a more zonal wave train is formed. Strong North American SAT WWCE dipoles and enhanced projections of PB-NAO + events onto the SAT WWCE dipole component are also readily seen for the positive North Pacific mode. The North Pacific mode seems to play a bigger role in the North American SAT variability than ENSO.
