**[Purpose of Cruise:]{.underline}**

To determine the vertical distribution of fish, zooplankton, and primary
producers in central Lake Erie relative to physical habitat features
(e.g., oxygen, temperature).

Objectives:

1.  Monitor 6 stations in central Lake Erie for 24 hours each using fish
    acoustics, a plankton survey system (PSS), zooplankton net and pump
    sampling, and a fast repitation-rate fluorometer (FRRP).

2.  Coordinate sampling with fish trawling efforts conducted by the R/V
    Laurentian, which will be operating in tandem with the Lake
    Guardian.

Environmental questions asked by the project:

> -How does low dissolved oxygen influence phytoplankton, zooplankton,
> and fish distributions, feeding behavior, condition, and production?

## Mooring Requirements:

No mooring experiments are currently planned for this cruise.

## Diving Operations:

No diving operations are currently planned for this cruise.

## Special Operating Requirements:

Our experimental site is actually a 3 nautical mile transect with
sampling occurring continuously along the transect, and at both ends
(\~1000 m outside the transect line). We will sample each 3 nautical
mile transect for 24 hr, with sampling blocks divided into the following
intervals (EDT): 0100-0500; 0500-0900; 0900-1300; 1300-1700; 1700-2100;
2100-0100. We would like to complete six 24-hour experiments at six
different sites in the central basin. Ideally, ship speed will be 4
knots, when on a transect.

**Sampling Protocol for Diel Experiment:**

At each station, we would like to do the following:

1.  With ship not moving (or only drifting), deploy PSS (from A-frame on
    stern to depth of 4 m) and acoustics (side from crane to depth of
    1 m) at \~1000 m before first station (i.e., outside transect line).

2.  Tow PSS and acoustics along a 3 nautical mile transect (ideally at
    \~4 knots, 5 knots max). Transect should take about 45-50 min. at 4
    knots. End at coordinates on the opposite end of transect.

    -   Please notify PSS and acoustics operators when 10, 5, 1 and then
        0 minutes from end of transect

    -   Continue steaming at 4 knots through the end of the transect
        until PSS is parked at a depth of 4 m

    -   Once up at 4 m, we will notify captain, who then can turn around
        and/or "park" ship \~1000 m from the end of the transect (i.e.,
        park ship outside of transect line)

> **PSS and acoustics equipment can remain in the water during the
> entire 24 hr sampling period, but should be pulled up during the steam
> to the next station.**

3.  Once at a stop and waters are settled, conduct a CTD cast to
    determine vertical structure.

4.  Use a rosette sampler to collect water at different depths (2-4
    depths)

5.  Two zooplankton net tows, full water column

6.  Pump for zooplankton at no more than 4 depths (to be determined from
    CTD cast).

7.  Deploy an 'optics rig' by means of vertical casts. The rig will
    include a Fast Repetition Rate Fluorometer (FRRF), a spectral
    fluorometer (Fluororobe), and a PAR meter. The instrument will be
    deployed at a rate of 4-5 m/min from surface to 1 m above bottom
    depth and back up at the same rate.

8.  Sit and wait until next cycle to start, per times above.

9.  Repeat the cycle until 6 cycles have been conducted at the site (24
    hr).

10. During each cycle in the daytime, we need an extra 30 minutes with
    acoustics over the side (at surface, but not towed) to calibrate the
    instrument. This can only occur in calm conditions.

11. Move to next station and repeat, until 6 stations are completed.

> **In theory, time will permit all stations to be sampled by morning of
> June 22. Below is the prioritizations of stations to be sampled (i.e.,
> 1^st^ stations are more important than last stations).**
>
> **1. FW-FE (note, this station is near a real-time buoy)**
>
> **2. BW-BE (note, this station is near a mooring)**
>
> **3. DW-DE (note, this station is near a mooring)**
>
> **4. CW-CE**
>
> **5. AW-AE**
>
> **6. GW-GE**

# Figure 1. We want to sample end point stations and tow the PSS and acoustics on the 3 nautical miles transects. Arrows and sequential numbers describe planned cruise track. Note, however, that station prioritizations are as follows, ranked from most important to least important (FW-FE; BW-BE; DW-DE; AW-AE; CW-CE; and GW-GE).
